The unequal-areas facility layout problem is concerned with finding the optimal arrangement of a given number of non-overlapping indivisible departments with unequal area requirements within a facility. We present an improved optimization-based framework for efficiently finding competitive solutions for this problem. The framework is based on the combination of two mathematical optimization mod...

The Locomotive Depot has a maintenance layout with 6 main lines as lines. of the facilities is also problem at Semarang Poncol locomotive depot because only 1 line can effectively carry out and repairs so this disadvantage dense queue locomotives wishing to be on duty carrying daily checks or monthly checks. that these 3 routes are often 2 which not maximized properly used place wait for repair...

in some instances, it is inevitable that large amounts of potentially hazardous chemicals like chlorine gas are stored and used in facilities in densely populated areas. in such cases, all safety issues must be carefully considered. to reach this goal, it is important to have accurate information concerning chlorine gas behaviors and how it is dispersed in dense urban areas. furthermore, mainta...

Nowadays, due to inherent complexity of real optimization problems, it has always been a challenging issue to develop a solution algorithm to these problems. Single row facility layout problem (SRFLP) is a NP-hard problem of arranging a number of rectangular facilities with varying length on one side of a straight line with aim of minimizing the weighted sum of the distance between all facility...

Teaching in formal academic environments typically follows a curriculum that specifies learning objectives that need to be met at each phase of a student’s academic progression. In this paper, we address the novel task of identifying document segments in educational material that are relevant for different learning objectives. Using a dynamic programming algorithm based on a vector space repres...

This paper proposes a new integrative view of manufacturing cell formation and both inter-cell and intra-cell layout problems. Cells formation and their popular bi-directional linear layout are determined simultaneously through a Dynamic Programming algorithm (with the objective of minimizing the inter-cell flow cost under a cell size constraint). This Dynamic Programming algorithm is implement...
