Here, we consider single vendor-buyer model with multi-product and multi-customer and multi-facility location-production-distribution problem. It is assumed that the players of the supply chain are coordinated by sharing information. Vendor manufactures produce different products at different plants with limited capacities and then distribute the products to the consumers according to determini...

this paper studies an m/g/1 repairable queueing system with multiple vacations and n-policy, in which the service station is subject to occasional random breakdowns. when the service station breaks down, it is repaired by a repair facility. moreover, the repair facility may fail during the repair period of the service station. the failed repair facility resumes repair after completion of its re...

In this paper, to cope with the stochastic dynamic (or multi-period) problem, two new quadratic assignment-based mathematical models corresponding to the dynamic and static approaches are developed. The product demands are presumed to be dependent uncertain variables with normal distribution having known expectation, variance, and covariance that change from one period to the next one, randomly...

We propose to implement a \multi-argus" facility at CFHT. The main scientiic driver of this project is the study of the evolution of the Tully-Fisher relation at intermediate redshift, thanks to the use of the optical rotation curves of spiral galaxies. The multiplex gain makes this project quite attractive, even on a 4m-size telescope such as CFHT. From the instrumental side, the idea is to mo...

Infectious waste disposal is a crucial concern in many areas. Not only the obnoxious, but it can also pose vital risk to human health. Disposal of infectious incurs higher costs than general and must abide by stricter regulations. In this paper, formulated as multi-objective optimization model. The objectives encompass economic, social, environmental concerns. To save cost, transshipment facili...

The use of the simulation-based technique in facility layout has been a choice in the industry due to its convenience and efficient generation of results. Nevertheless, the solutions generated are not capable of addressing delays due to worker’s health and safety which significantly impact overall operational efficiency. It is, therefore, critical to incorporate ergonomics in facility design. I...
