There are varieties of QFD combination forms available that can help management to choose the right model for his/her types of problem. The proposed MOCC-QFD-FMEA model is a right model to include variety of objectives as well as the risk factors into the model of the problem. Due to the fact that the model also takes into consideration the concept of Fuzzy set, it further allows management...

Mathematical programming and artificial intelligence (AI) methods are known as the most effective and applicable procedures to form manufacturing cells in designing a cellular manufacturing system (CMS). In this paper, a bi-objective programming model is presented to consider the cell formation problem that is solved by a proposed multi-objective particle swarm optimization (MOPSO). The model c...

background and objectives: in this paper, a real life nurse scheduling model is described based on the conditions in iranian hospitals such as monthly shift rotation, consecutive morning and evening shifts and consecutive evening and night shift.   methods: the developed model considers both hospital constraints and nurses’ preferences. hospital constraints include assigning adequate qualified ...

Scheduling problem for repetitive construction projects involves three conflicting objectives. These objectives are project duration, project total cost, and project total interruption time. This paper presents a multi-objective fuzzy linear programming model (FLP) for resolving this problem. Literature concerned with scheduling problems for repetitive construction projects was reviewed. Multi-...

A comprehensive and integrated study of any supply chain (SC) environment is a vital requirement that can create various advantages for the SC owners. This consideration causes productive managing of the SC through its whole wide components from upstream suppliers to downstream retailers and customers.  On this issue, despite many valuable studies reported in the current literature, considerabl...

today, due to rising passenger expectations and other resource constraints, the airport managers and staff do to develop appropriate programs in order to optimize the allocation of the resources. gates and counters are important resources in airport. in this research problem of gate and counter for arrival flights is considered simultaneously and mathematical model is prepared. the objectives o...
