The Single Row Facility Layout Problem (SRFLP) is the problem of arranging n departments with given lengths on a straight line so as to minimize the total weighted distance between all department pairs. We present a polyhedral study of the triplet formulation of the SRFLP introduced by Amaral [Discrete Applied Mathematics 157(1)(2009)183-190]. For any number of departments n, we prove that the ...

The single-row facility layout problem (SRFLP) is concerned with finding the optimal linear placement of n departments with different lengths in a straight line. It is typically achieved by minimizing the cost associated with the interactions between the departments. The semidefinite programming (SDP) relaxation model that incorporates cutting planes proposed recently by Anjos, Kennings, and Va...

The facility layout problem is a global optimization problem that seeks to arrange a given number of rectangular facilities so as to minimize the total cost associated with the (known or projected) interactions between them. This paper is concerned with the single-row facility layout problem (SRFLP), the one-dimensional version of facility layout that is also known as the one-dimensional space ...

This paper considers a double-row layout problem with shared clearances in the context of semiconductor manufacturing. By sharing some clearances, reductions in both layout area and material handling cost of approximately 7–10% are achieved. Along with minimal clearances for separating adjacent machines, clearances that can be shared by adjacent machines are considered. The shared clearances ma...

A facility layout problem is concerned with determining the best position of departments, cells, or machines on the plant. An efficient layout contributes to the overall efficiency of operations. It’s been proved that, when system characteristics change, it can cause a significant increase in material handling cost. Consequently, the efficiency of the current layout decreases or is lost and it ...

The facility layout problem is one of the fundamental production system management problems. It has a significant impact on overall efficiency. This paper introduces new that allows for choosing from multiple variants each facility. need most suitable selection while at same time optimizing other quality indicators represents optimization challenge. We build our previous work where single- and ...

For machining workshops that use automated guided vehicles (AGVs) for material handling and management, workstation layout AGV path are coupling factors affecting the cost (MHC). The multi-row is a typical pattern in many workshops, currently, there lack of studies on problem (MRLP) while taking into account path. This study established bi-objective optimization methodology integrating to minim...

This paper presents an algorithm for solving a multi-floor facility layout problem. The most apparent difference and also the potential difficulty in a multi-floor facility layout problem, compared to a single floor facility layout problem, are the problems regarding the placement of the vertical transportation equipments (elevators), which are to be used for vertical transportation occuring wi...
