Designing an operations research course under active learning strategies
(American Society for Engineering Education, ASEE, 2002-06-16) Rivera Cadavid, Leonardo
Various activities and resources that are considered useful for an operations research (OR) class in Icesi University are discussed. The OR class is being offered today to business, industrial engineering, computer engineering and telecommunication engineering majors. The Icesi University is convinced that Active Learning is useful for its students' formative process. It is necessary that the Department Heads on each academic area work with their faculty in the development of curricula that formally introduces these concepts to each of the courses.
Cost-time profiling: Putting monetary measures onto value stream maps
(2006-05-20) Rivera Cadavid, Leonardo
The Cost-Time Profile (CTP) is a tool that presents graphically the accumulation, of direct costs on a product as it moves through the manufacturing process. CTP incorporates the time dimension, to the cost accumulation, and the area under the CTP curve is the Cost-Time Investment (CTI), which is a measure of the investment of resources on the manufacturing of the product. In this paper, a general overview of the CTP, its construction, applications and future research directions are presented.
Beyond Partnerships: The Power Of Lean Supply Chains
(Springer London, 2007-01-01) Chen, F. Frank
Extending the value stream from a lean company to its partners allows the company to widen the pursuit for perfection to the whole supply network. Furthermore, applying lean concepts to a supply chain opens new windows of opportunity for supply chain participants to collectively achieve higher levels of competitiveness. Thus, the integration of supply chain management and lean thinking covers both local and overall leanness, which leads to a truly lean supply chain. This chapter provides an overview of the lean supply chain, the including concepts, approaches, challenges, and future development. In the first part of the chapter, basic concepts and impacts of lean thinking will be introduced, followed by the issues of applying lean thinking in supply chain management. Then, an integrated framework of a lean supply chain will be presented. The second part of the chapter covers the building blocks of lean supply chains, including lean logistics, information technology, performance measurement and improvement, and collaboration beyond partnerships. Subsequently, the challenges for building or maintaining a sustainable lean supply chain will be discussed.
Leanness score of value stream maps
(2007-05-19) Wan, Hung Da
A Value Stream Map (VSM) allows lean practitioners to visualize the performance and conditions of manufacturing systems. While creating visibility for improvement plans, a measure of overall leanness level is not inherent in the map. This research proposes a methodology to measure the overall leanness of a VSM considering Cost, Time and output Value. Value-added and non-value-added investments are identified to quantify the level of leanness. Using the Data Envelopment Analysis technique, the leanness measure delivers a self-contained, unit-invariant score of the mapped system to support decision making on continuous improvement.
Simulation as an intuition building tool for factory physics
(Society for Computer Simulation International, 2007-07-18) Summer Computer Simulation Conference
In today's manufacturing environment it is absolutely critical to be competitive in order to guarantee a company's sustainability. One way to achieve this sustainability is to count on management's ability to effectively make decisions dealing with its manufacturing resources. To do this management must rely on a systematic description of the manufacturing system and a set of performance measures used to evaluate and control the system. One way to do this is to employ the concepts and laws of Factory Physics. These concepts and laws can become very powerful tools to identify and understand a system's weak points, permitting management to design ways to turn them into leverage points. But to do this management needs to have good intuition and this can only be done if it fully understands the meaning of these concepts and laws. In order to facilitate the understanding of Factory Physics a computer based simulation model was developed as part of a learning tool to be used in conjunction with a formal Factory Physics course. This paper examines the model and its usefulness as a learning tool.

Activity scheduling for Cost-Time investment optimization in project management
(2008-05-17) Rivera Cadavid, Leonardo
The Cost-Time Profile is a tool that presents the combined impact of disbursements made during the execution of a project, and their timing. The Cost-Time Profile chart presents the accumulated cost at any given time, and the area under the curve is the Cost-Time Investment. This Cost-Time Investment has a quantifiable impact on the working capital the company uses, and it is also useful for the determination of the Direct Cost of a product. This paper aims to develop a model to create the schedule of activities that minimizes the Cost-Time Investment for a project.

Technology assessment for an inventory management process in a hospital unit
(Institute of Industrial and Systems Engineers (IISE), 2009-05-01) Rardin, Ronald
The penetration of Auto Identification and Data Capture Technology (Auto ID DC) in healthcare logistics is low. A recent American Health Association ( AHA) study shows that 16% of hospitals use barcode technology for supply chain management purposes, and 3% use Radio Frequency Identification (RFID). Hospital materials managers find it difficult to evaluate the impact of Auto ID DC technologi es on current processes in or der to make a decision about whether or not to adopt a technological alternative. This paper studies the impact of Auto ID DC technologies on the inventory management process in a hospital unit. In particular we will refer to implantable devices within a catheterization lab. We propose a conceptual design of the system and a quantitative modeling approach to handle these issues, and present our preliminary results from a spreadsheet-based tool.
Applying systems thinking and active learning strategies to a lean manufacturing program
(Proceedings Of The 21st Annual Conference Of The Production And Operations Management Society, 2010-05-07) Rivera Cadavid, Leonardo
Lean Manufacturing seeks to eradicat e waste. This pursuit is conducted changing many pre-conceptions inherited fr om the mass production traditions. It is necessary to understand immediate and delayed impacts of the changes, as well as direct and indirect results of these changes. Th is systemic approach should enhance the learner’s understanding of the system (the manufacturing company) , its variables, its outcomes, and the relationships among the system’s components. This paper presents the process of designing a course to teach Lean Manufacturing to working professionals using systems thinking. This design proce ss is conducted for the development of job competencies and using Active Learning Strategies.
Modeling the adoption of identification standards in US hospitals: A systems dynamics approach
(Institute of Industrial Engineers, 2011-01-01) Rardin, Ronald
This paper summarizes the findings related to the current modeling efforts of identification standards adoption using a system dynamics SD modeling approach. A literature review on technology adoption provides the basis for the decision to utilize the SD approach. The SD model builds off previous findings related to the factors affecting identification standards adoption and relates the specific elements to the adoption rate. These elements are introduced in the model using a causal loop diagram, and then a stock flow model is constructed based on the Bass diffusion model. The model is used to simulate the behavior of the hospital population over time and to observe the impact of the external and internal diffusion coefficients in the adoption rate. Initial efforts focus on the provider perspective but other healthcare supply chain members can be introduced in the model due to its flexibility. The SD model allows for the analysis and design of policies to move the adoption process forward. The preliminary findings are discussed along with the implications on subsequent modeling efforts.

A levels, readiness, and impact evaluation model for GS1 adoption in healthcare
(Institute of Industrial Engineers, 2011-05-21) Lehlou, Nabil
The use of GS1 data standards is envisioned to improve the efficiency of healthcare supply chain, as it did for retail. Care providers willing to adopt such a strategy in some or all of their operations often need to invest in process changes and technological installations or upgrades; however, they struggle to project returns on those investments and hence, find uncertain ROI a barrier to adoption. We present a hierarchical comprehensive model that helps potential adopters of various parts of the standards (what we term levels) evaluate their readiness requirements and quantify the impacts of their potential decisions in terms of non-monetary performance measures, such as productivity. The model design is showcased through practical examples.
Data standards in healthcare supply chain operations
(Institute of Industrial Engineers, 2011-05-21) Dixon, Danny
This paper presents the challenges and benefits associated with adoption of healthcare supply chain data standards in a hospital environment. In a highly fragmented industry like healthcare with several stakeholders, the adoption and use of common data standards for identifying delivery locations and products is critical. Common data standards ensure system wide interoperability and visibility across the supply chain, contributing to improvements in patient safety and streamlined internal and external supply chain operations. However, the global healthcare industry has been significantly slow in adopting data standards in comparison to other industries like retail, manufacturing. We discuss the results from data standard adoption pilot project conducted by Center for Innovation in Healthcare Logistics (CIHL), University of Arkansas at Washington Regional Medical Center, a 325 bed not-for-profit hospital in Fayet-teville, Arkansas. CIHL data standards pilot involved studying the existing supply chain processes, design, pilot-test, and evaluation of GS1 data standards adoption over a sample of products and a single delivery location at the hospital. We present the results, which demonstrate the capabilities of systemwide improvements and roadblocks likely to be encountered. Findings from the pilot can be expanded to develop a broad implementation plan of data standards adoption for healthcare providers.
Stocks Of Knowledge And Organizational Performance: Dynamic Relationship
(System Dynamics Society, 2011-07-22) Arenas Guerrero, Fernando Antonio
The relationship between the level of knowledge and organizational performance has been studied by the academic commun ity and is receiving growing attention from decision makers in organizations. However it is not the case of the feedback relationship between performance and the level of knowledge, although this relationship has a dynamic pattern of behavior on both variables. This research poses a conceptual approach that involves a causal model of this feedback relationship, theoretically founded on the resource based view and the behavioral theory of the firm. The methodology involves the design and use of a system dynamics simulation model based on a pharmaceutical comp any which relates stocks of knowledge, innovation capability, financial performance and investments on knowledge stocks.
This videogame is just like my plant!
(ASEE Annual Conference and Exposition, 2012-06-13) López, Andrés; 119th ASEE Annual Conference and Exposition
This paper presents a learning experience that was developed using the commercial videogame Rise of Nations for a graduate course on Manufacturing and Operations Strategy. This is a historical strategy game in which players compete by taking civilizations through progressive development stages. The game was employed under the Serious Games paradigm, in which a game is considered serious when it is used with an objective other than entertainment. This paper explains the objectives of the use of the game in the class, the regulations and learning guides that were employed, the experiences the students lived, the main points the students take away from the use of the game and other experiences that take place in the class in addition to the delivery of contents and development of skills. This experience took place at Universidad Icesi, in Cali, Colombia. © 2012 American Society for Engineering Education
Parámetros óptimos para geometría de bodegas no tradicionales
(2012-08-29) Cardona, Luis Felipe
Tradicionalmente las bodegas han sido diseñadas bajo dos supuestos tácitos, los pasillos de picking son paralelos unos de otros y los pasillos atravesados son perpendiculares a los pasillos de picking. El Fishbone layout es un diseño no tradicional para bodegas de carga unitaria que replantea estos supuestos y logra mejorar la productividad aproximadamente en un 20%. Este proyecto desarrolla un estudio analítico del Fishbone layout, presentando alternativas para diferentes situaciones de interés en el sector real. El proceso de diseño se plantea como un problema de optimización no lineal y se concentra en la característica más importante del Fishbone layout, la pendiente del pasillo diagonal. Finalmente, el autor presenta una expresión analítica para la pendiente del pasillo diagonal y un análisis de sensibilidad que muestra la robustez del diseño.
Preparing for end of service life of wind turbines
(2013-01-01) Nies, Loring F.
The wind power industry is growing rapidly. Wind turbines (WTs) are perceived as a low environmental impact energy generation technology. While the service life of a WT is relatively long (20-40 years), at some point a significant number of WTs will reach the end of their service lives. To recover maximum value from these WTs, planning for the end-of-service life of wind turbines (EOSLWTs) is paramount. Historically, environmental life cycle assessments of WTs have often only considered the materials extraction and processing, manufacturing, and use phases, leaving the management of EOSLWTs outside the scope of their attention. Four key EOSLWTs issues that are essential for the continuing development of wind energy technologies are presented: i) The challenges of managing of EOSLWTs given the fast growth rate of the industry and the large number of existing installed WTs; ii) The EOSLWT alternatives such as remanufacturing and recycling to recover functional and material value respectively; iii) The critical activities in the WT reverse supply chain such as recovery methods, logistics of transportation, quality of returns, and quality of reprocessed WTs; and iv) The economic and business issues associated with EOSLWTs. It is expected that the discussion provided will stimulate a dialog among decision makers and raise awareness of economic opportunities and unanticipated challenges in the wind power industry. © 2012 Elsevier Ltd.

Aproximación al desarrollo de un sistema de transporte masivo a través de la dinámica de sistemas
(Universidad Icesi, 2013-01-01) Arenas Guerrero, Fernando Antonio; Orozco, Juan Sebastián
The social and economic future of a city depends primarily on the efficiency of its transport system; this is measured by the ability to move people and goods in a sustainable manner, with the available resources. Nowadays, Mass Transit systems are being developed in seven different cities of Colombia, which have created the need to track the progression and growth of their participation in the one-person travel demand. The purpose of this work is to describe the development of a mass transit system, and to provide an overview of the impact that the operating parameters and reinvestment have on the development and expansion of the demand of the system itself. Three scenarios are proposed to evaluate different operational and reinvestment policies, analyzing the behavior in the development of the system.
