Purpose
This study aims to address challenges related to long lead time within a hazelnut company, primarily attributed to product quality issues. The purpose is to propose an integrated lean-based methodology incorporating a continuous improvement cycle, drawing on Lean Six Sigma (LSS) and Industry 4.0 applications.

In this paper, a multi-objective hybrid flowshop scheduling problem (HFSP) with limited waiting time and machine capability constraints is addressed. Given its importance, the implementation of lot streaming division methodologies with the problem is investigated through a design of experiment (DoE) setting based on real data extracted from a leadi...
An emerging question for photovoltaic (PV) solar power development is how to ascertain the optimal choice from a finite set of available alternatives under numerous conflicting criteria as well as high levels of imprecise, vague, and uncertain information. For the first time, we investigate the prioritization of the alternatives for the development...
Drawing upon economic and environmental sustainability, this study explores how developing the operational resilience of the medical supply chain (MSC) contributes to maintaining healthcare in the face of disruption risks, such as the COVID-19 pandemic. To this end, an optimization-based roadmap is proposed by employing lean tools to achieve and re...
The devastating impact of the ripple effect increases the importance of the reverse supply chain (RSC) design to ensure sustainability in the long-term. That being the case, in this study, a two-stage stochastic mixed-integer optimization model is proposed to design an RSC network under uncertainty sourcing from the ripple effect (i.e. external sid...
This chapter proposes a comprehensive methodology to design a customer-oriented production system. To this end, an axiomatic design (AD) based methodology is developed by employing one of the most widely used lean techniques, value stream mapping (VSM). The methodology is designed in three stages: (i) analyzing the current state, (ii) applying the...
The machine selection process has been an important issue for companies for many years. The wrong selection of the machine leaves a negative result on the efficiency, precision, flexibility, and sensitive production capacity of the company, and this leads to many problems. In this study, a real case application in a company that serves in the wood...
This study examines the ripple effect on the system performance of the reverse supply chain (RSC) network and introduces a robust optimisation model for designing strong RSC networks to cope with the uncertainties caused by the ripple effect. In this manner, to the best knowledge of authors, a robust optimisation model for RSC design against the ri...
This paper addresses a lean holistic fuzzy methodology for the new product development (NPD) projects to cope with the uncertainties encountered in the projects by placing an emphasis on the cross-functional worker teams along with utility workers’ impact on the lead time and total operational cost. To this end, the fuzzy design structure matrix (F...
The paper presents a fuzzy extension of CODAS (COmbinative Distance-Based ASsessment) method which is called as interval-valued Atanassov intuitionistic fuzzy CODAS (IVAIF-CODAS) method for group decision making processes. The extended method considers interval-valued Atanassov intuitionistic fuzzy sets (IVAIFSs) to define the judgements of decisio...
As the first and the most time consuming step of product recovery, disassembly is described as the systematic separation of constituent parts from end-of-life products through a series of operations. In this context, designing and balancing disassembly lines are critical in terms of the efficiency of product recovery. Recent research on disassembly...
All organizations have to get qualified and professional human resources because of the increasing competition conditions and technological improvements recently. Companies can manage this situation by selecting the most appropriate candidates for jobs or tasks featly. Personnel selection is a crucial and compelling process. The main goal is to ass...
As the product life cycles have continuously decreased, disassembly system design has been regarded to be important for manufacturing enterprises. Effective design of a disassembly system enables the enterprises to recycle the end of life products with low cost and high utilization of labors. This study focuses on line segmentation problem of disas...
As a result of the rapid development of technology and innovation, new products are being introduced into the market incessantly and cause the products on the market to quickly get old and unpopular. This ongoing competition forces companies to develop new products in less time to meet the needs of customers. In this context, optimization of new pr...
The Hub Location-Allocation Problem is one of the most important topics in industrial engineering and operations research, which aims to find a form of distribution strategy for goods, services, and information. There are plenty of applications for hub location problem, such as Transportation Management, Urban Management, locating service centers,...
