Sewing Machine Selection Using Linear Physical Programming

Abstract

Sewing is a critical operation in garment production process. Therefore, alternative sewing machines must carefully be evaluated prior to procurement. Multiple criteria decision making (MCDM) techniques can effectively be used in sewing machine evaluation process since multiple evaluation criteria including speed and price must be considered. However, physically meaningless subjective weights are assigned to evaluation criteria in most MCDM techniques. Linear Physical Programming (LPP) is a MCDM methodology that eliminates this subjective weight assignment process by allowing decision makers to express their preferences in a physically meaningful way. In this study, a sewing machine selection problem faced by a textile company is solved using LPP.

Regional Aircraft Selection With Fuzzy Piprecia and Fuzzy Marcos: A Case Study of the Turkish Airline Industry

“…These cover a wide range from simple procedural decisions to large investment decisions. One of the risky investment decisions is aircraft selection, which can affect the sustainability and competitive ability of airlines [19]. Aircraft selection problem, which has a quite high investment amount, is a process that is affected by many different factors such as business strategies, passenger needs, government policies [7].…”

“…At this point, a number of tools that enable DMs to make effective and efficient decisions are highly beneficial. Due to the multiple criteria nature of the aircraft selection problem, MCDM techniques come to the fore in this regard [19]. MCDM techniques have been frequently used in aircraft selection problems in the aviation industry.…”

“…In addition, cargo aircraft [27], long-haul aircraft [28], medium-haul aircraft [9,25,29], and short-haul aircraft [26] selection studies have been conducted by detailing the aircraft selection problem. Methodologically, prior research employed numerous techniques, including AHP and TOPSIS in interval type-2 fuzzy sets [9], fuzzy AHP [7,8,26], fuzzy TOPSIS [23,30], fuzzy AHP and TOPSIS [24], AHP and even swaps method (ESM) [5], SWARA and SMAA-2 method [22], an integrated AHP, COPRAS, and MOORA methodology [25], fuzzy AHP and fuzzy grey relational analysis (GIA) [27], linear physical programming [19], AHP [20], NAIADE (Novel Approach to Imprecise Assessment and Decision Environments) [31], FUCOM and ARAS [21], fuzzy AHP and fuzzy ANP [29], ELECTRE, SAW, and TOPSIS [28], ANP [32], and fuzzy reference ideal method (FRIM) [33]. In Table 1, the aircraft selection literature is depicted by detailing research purposes and criteria sets.…”

SVNSs can be considered as a subclass of NSs.…”

“…Aircraft selection can be taken as the most important investment decision for airline companies due to having an effect on the type and quality of services presented to customers [13]. Aircraft selection is a complex system engineering that includes aircraft parameters, engine performance, communication and navigation technology, flight dynamics, meteorology, art design, financial management, and corporate strategic planning [14].…”
