background: conventional health, safety and environment (hse) are a widely used approach to enhance availability and efficiency of complex systems. the integrated hsee system is defined however as integration of conventional hse with ergonomics approach. the presented hsee system introduces a unique, effective and systemic mechanism, which integrates the structure of the human and organizationa...

In this paper, teaching–learning-based optimization (TLBO) is proposed to solve flexible job shop scheduling problem (FJSP) based on the integrated approach with an objective to minimize makespan. An FJSP is an extension of basic job-shop scheduling problem. There are two sub problems in FJSP. They are routing problem and sequencing problem. If both the sub problems are solved simultaneously, t...

background: the objectives of this paper are three folds. first, an integrated framework for designing and development of the integrated health, safety and environment (hse) model is presented. second, it is implemented and tested for a large gas refinery in iran. third, it is shown whether the total ergonomics model is superior to the conventional ergonomics approach. this study is among the f...

In this paper, we propose a new model for designing integrated forward/reverse logistics based on pricing policy in direct and indirect sales channel. The proposed model includes producers, disposal center, distributers and final customers. We assumed that the location of final customers is fixed. First, a deterministic mixed integer linear programming model is developed for integrated logistic...

The synthesis of heat integrated multi-component distillation systems is complex due to its huge search space for structural combination and optimization computation. To provide a systematic approach and tools for the synthesis design of distillation systems, a new method for modeling heat integrated columns is presented, and the operating cost objective function is minimized by improved harmon...
