In domains such as automotive or avionics, software cannot any longer be produced as a single chunk, and engineers are contemplating the possibility of componentizing it. A component only exhibits its provided or required interfaces, which must be enriched to take into account extra-functional aspects. This defines multi-level contracts between components allowing one to properly wire them. Ins...

One of the most fundamental components of healthcare system on each country is blood supply chain management. This chain is comprised of two significant components including collecting donor’ bloods and supplying blood’s products. The main purpose of this paper is to concentrate on supplying blood products and present a novel constrained bi-objective mathematical model for a two-echelon blood s...

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...

This paper introduces a multi-factory scheduling problem with heterogeneous factories and parallel machines. problem, as major part of supply chain planning, includes the finding suitable factory for each job assigned jobs at factory, simultaneously. For first time, this studies multi-objective in production network which has its customers demands can be satisfied by itself or other factories. ...

The design change propagation in a complex product is characteristic of nonlinear, dynamic, and uncertain; its impact analysis becomes challenging. Furthermore, the multiple changes occurring concurrently during the whole design process increase the difficulty of the change propagation analysis. In this article, a new change propagation prediction method based on multi-agent system, especially ...

Group-living animals often exhibit complex collective behaviors that emerge through the non-linear dynamics of social interactions between individuals. Previous studies have shown that it is possible to influence the collective decision-making process of groups of insects by integrating them with autonomous multi-robot systems. However, generating robot controller models for this particular tas...

This paper addresses a highly challenging scheduling problem in the field of printed circuit board (PCB) assembly systems using Surface Mounting Devices (SMD). After describing some challenging optimization sub-problems relating to the heads of multi-head surface mounting placement machines, we formulate an integrated multi-objective mathematical model considering of two main sub-problems simul...

This paper presents a new mathematical model for a bi-objective job shop scheduling problem with sequence-dependent setup times that minimizes the weighted mean completion time and the weighted mean tardiness time. For solving this multi-objective model, we develop a fuzzy multi-objective linear programming (FMOLP) model. In this problem, a proposed FMOLP method is applied with respect to the o...

this research, for the first time presents the flexible flow shop model of scheduling method for considering runway assignment and operations planning together. one of the advantages of the developed model is considering the procedures of air routes in terminal airspace and separation between consecutive aircraft which is very similar to the real world condition. there are different objective f...
