A multi-criteria decision-making framework for assessing the quality and cost of facility layout alternatives: a case study

Abstract

The paper presents a multi-phase framework for assessing the quality and cost of facility layout alternatives. The framework utilizes life-cycle cost analysis (LCCA) and multicriteria decision-making (MCDM) to account for economical and qualitative aspects. Lifecycle considerations include costs of development, investment, construction or production, usage, and scrapping. A test of the proposed framework was performed at the Swedish Mail Terminal in the town of Alvesta, a part of Posten Sweden AB. The terminal has several space, machine, and operational constraints. Three layout alternatives were developed and evaluated using the suggested framework. Although the selected layout alternative has the highest implementation cost, it yields a 9 per cent better total life-cycle cost than the closest alternative based on a ten year life-cycle length. The originality of this approach is evident in addressing both quantitative and qualitative facility planning issues such as economical and non-economical aspects, using both LCCA and MCDM methodologies. The approach proposed in this paper is not only valuable in this case study, but it can also be generally applied in other similar decision situations.

The Life Cycle of the Layouts of Flexible and Reconfigurable Manufacturing Areas and Lines

“…Collaborative engineering means that product development and manufacturing development take place in parallel. Design for manufacturing means that technological possibilities and capabilities are considered in the design through continuous interaction [1,2]. From the product design side, the following information may be important for production planning and layout planning:…”

A hybrid optimization approach for unequal-sized dynamic facility layout problems under fuzzy random demands

“…Facility layout greatly influences the production system in terms of material handling costs, lead time, and work-in-process (WIP) inventory. 1 It is a long-standing research topic involving the physical arrangements of a number of non-overlapping facilities including workstations, machines, and utilities. 2 Material handling costs are one of the most crucial factors to measure the rationality of a layout since they account for 20%-50% of the overall operating costs and 15%-70% of the total manufacturing costs.…”

Supplier selection based on evidence theory and analytic network process

“…The supplier selection is a multi-criteria decision-making (MCDM) problem. A number of MCDM methods have been proposed, 1,2 including analytic hierarchy process (AHP), 3,4 analytic network process (ANP), 5 technique for order of preference by similarity to ideal solution (TOPSIS) 6,7 and others. 8 The AHP is a structured technique for organizing and analyzing complex decisions, developed by Saaty 9,10 in the 1970s.…”
