Semiconductor manufacturing is one of the most complex and capital-intensive processes composed of several hundreds of operations. In today's competitive business environments, it is more important than ever before to manage manufacturing process effectively to achieve better performances in terms of customer satisfaction and productivity than those of competitors. To obtain such fruitful outco...

This paper addresses a multi-period, multi-product sawmill production planning problem where the yields of processes are random variables due to non-homogeneous quality of raw materials (logs). In order to determine the production plans with robust customer service level, robust optimization approach is applied. Two robust optimization models with different variability measures are proposed, wh...

We display how LSCs can be used to analyze a production line systematically and synthesize a scheduler from the model. This work demonstrates how the features of a scenario based object oriented modeling language are exploited in this domain. It also shows advantages of the play-in/play-out methodology combined with verification methods. Planning a production line with LSCs ∗ Hillel Kugler and ...

Production planning and production control mainly focus on optimising the entire production system of a company. On the basis of hierarchical planning as a suitable method for solving this task, this paper shows besides the economic dimension taken into account so far that there are also social and ecological effects which will have to be considered in the process of planning. For this purpose,...

Multiagent Systems (MAS) are a computational paradigm in which several semi-autonomous agents interact with each other, either to solve a problem or achieve a number of individual or collective goals. Moreover, the production planning is a key activity in performance of the industry, so it is evident the need for applications that provide support in the development of these activities, to achie...

EXECUTIVE SUMMARY This case details the implementation of the Systems Applications & Products (SAP) Production Planning module at EA Cakes Ltd. The market forced the company to change its sales and production strategy from “make-to-order” to “make-to-stock.” The decision to change the strategy involved not only the company’s decision to invest much more money in accumulation and keeping stocks ...

Due to the increase of a variety of demands from downstream customers, the enterprises are necessary to expand more capacity of their factories by way of adding more plants or outsourcing. Many enterprises encounter great difficulties in production planning because manufacturing environments have changed from traditional single-plant to current multi-plants. Therefore, the company may possess m...

perishability of blood products as well as uncertainty in demand amounts complicate the management of blood supply for blood centers. this paper addresses a mixed-integer linear programming model for blood platelets production planning while integrating the processes of blood collection as well as production/testing, inventory control and distribution. whole blood-derived production methods for...
