Product Line Design for Profit Maximization Using Common Parts, Features and Manufacturing Facilities
OPSEARCH - Tập 38 - Trang 596-611 - 2017
Designing products is an important managerial problem. In literature, we see this reflected essentially as engineering and marketing issues. However, this problem is tackled in isolation from each other and related production issues, resulting in products which require distinct parts, features and production facilities resulting in higher direct product and manufacturing costs than necessary. The ...... hiện toàn bộ
Mixed symmetric duality for nondifferentiable programming problems
OPSEARCH - Tập 43 - Trang 296-308 - 2017
A pair of nondifferentiable mixed symmetric dual programming problems is introduced and duality theorems are proved. This unifies two existing formulations of symmetric dual problems appeared in the literature.
A heuristic for single machine common due date assignment problem with different earliness/tardiness weights
OPSEARCH - Tập 60 - Trang 1561-1574 - 2023
This paper considers the common due date assignment for single machine weighted earliness/tardiness scheduling problem with different earliness and tardiness weights for jobs where the objective is to minimize the cost of the sum of weighted earliness/tardiness and assignment common due date. The single machine common due date assignment problem where all jobs have the same earliness/tardiness wei...... hiện toàn bộ
Solving a bi-objective mixed-model assembly-line sequencing using metaheuristic algorithms considering ergonomic factors, customer behavior, and periodic maintenance
OPSEARCH - Tập 58 - Trang 513-539 - 2020
In today’s competitive world, companies must maintain their customers and attract new ones. Hence, they paid a great attention paid to mixed model assembly lines (MMAL). In this study, a two-step framework was developed to investigate and optimize customer relationships and the sequence of orders in an MMAL. First, based on customers past behavior, they were grouped into three clusters with high, ...... hiện toàn bộ
Maintenance of Deteriorating Systems Subject to Shocks
OPSEARCH - Tập 37 - Trang 259-266 - 2017
In this article we analyze a stochastic model for a maintained system which deteriorates as a result of the cumulative effects of random shocks. Each arriving shock results in a unit decrease in the state of the system, representing its residual life time. The system is repaired by a repairman arriving according to Poisson process. On arrival, if he finds the state of the system below a safety lev...... hiện toàn bộ
A novel goal programming approach based on accuracy function of pythagorean fuzzy sets
OPSEARCH - - 2023
Goal programming (GP) is a well-established optimization methodology used to solve multi-objective problems. This paper outlines a novel goal programming approach that aims to improve the effectiveness of the traditional intuitionistic goal programming method. The proposed approach incorporates the concept of pythagorean fuzzy logic. Accuracy function of the pythagorean fuzzy sets has been used to...... hiện toàn bộ
Machine repair problem with an unreliable server and controlled arrival of failed machines
OPSEARCH - Tập 51 Số 3 - Trang 416-433 - 2014
Multi-criteria trapezoidal valued intuitionistic fuzzy decision making with Choquet integral based TOPSIS
OPSEARCH - Tập 51 - Trang 98-129 - 2013
A generalized trapezoidal-valued intuitionistic fuzzy geometric aggregation operator is proposed which is then used to aggregate decision makers’ opinions in group decision making process. An extension of TOPSIS, a multi-criteria trapezoidal-valued intuitionistic fuzzy decision making technique, to a group decision environment is also proposed, where inter-dependent or interactive characteristics ...... hiện toàn bộ
