Planning that incorporates critical resource and part constraints due to manufacturing processing as well as material handling tolerance and kinematic requirements has not been reported in the existing literature. By integrating these manufacturing resource and part constraints using object-oriented design, our new operations planner creates immediately executable manufacturing plans for flexib...

Scheduling problems play a big role in manufacturing and planning the production for increasing the production efficiency and assigning the resources to operations. Furthermore, in many manufacturing systems there is a physical space between stages that called intermediate buffers. In this study, a model is proposed for minimizing the makespan of a hybrid flow shop scheduling problem with inter...

Multitasking is an important part of today’s manufacturing plants. Multitask machine tools are capable of processing multiple operations at the same time by applying a different set of part and tool holding devices. Mill-turns are multitask machines with the ability to perform a variety of operations with considerable accuracy and agility. One critical factor in simultaneous machining is to cre...

A mathematical framework which has been speci cally developed for manufacturing-like systems is presented, focusing on time-free dynamics and control, as treated by Finite State Automata. The approach is based on the key concepts of object types, locations and manufacturing operations enriched with an algebra (Manufacturing Algebra) for building complex operations as algebraic series-parallel c...

This paper describes manufacturing operations design and analysis at Intel. The complexities and forces of both the market and the manufacturing process combine to make the development of improved semiconductor fabrication manufacturing strategies (like lot dispatching, micro and macro scheduling policies, labor utilization, layout, etc.) particularly important. We present modeling as an effect...

Over the past decade, there has been a growing need to use computers in the educational process. Software developers have started to take advantage of the most significant advances in computer technology most notably, internet-based networks. Undeniably, the Internet will be a vital part of education in the future. VRML or Virtual Reality Modeling Language is one of the many potential education...

A manufacturing system is a product, and has to be designed as any other product. Therefore, a need for adequate methodological support and tools for modeling, structuring, and control of the next generation manufacturing systems is recognized. In this study, the adaptive distributed modeling framework for collaborative design and operations of network manufacturing systems is presented. In man...

We study a variant of the Stochastic Economic Lot Scheduling Problem (SELSP) in which a single production facility must produce several grades to meet random stationary demand for each grade from a common finished-goods (FG) inventory buffer with limited storage capacity. Demand that can not be satisfied directly from inventory is lost. Raw material is always available, and the production facil...

This special issue is related to the XIV Latin-Ibero-American Conference on Operations Research (CLAIO-2008) held in Cartagena de Indias, Colombia, September 9–12, 2008. The meeting was hosted by the Colombian Society for Operations Research (SOCIO) and the Latino-Ibero American Association for Operations Research (ALIO) and was jointly organized by four Colombian universities: Universidad del ...
