We consider a robotic ow shop model in which a single robot is responsible for the transportation of parts between machines. For reasons of simplicity, when the shop is to produce a large number of identical parts, the robot usually performs repeatedly a xed sequence of activities. This sequence of activities is called a 1-unit cycle if each execution of the sequence results in the production o...

In a shop floor of the industry, the routings which are based upon the jobs that need to be processed on different machines are one among the major activities and therefore the resource requirements are not based upon the quantity as in a flow shop but rather the routings for the products being produced. However, both job shop and flow shop production cope with a scheduling problem to find a fe...

In this paper, two methods named distance and triangle methods are extended to evaluate the quality of approximation of the Pareto set from solving bi-objective problems. In order to use evaluation methods, a bi-objective problem is needed to define. It is considered the problem of scheduling jobs in a hybrid flow shop environment with sequence-dependent setup times and the objectives of minimi...

In this paper, cellular manufacturing scheduling problems are studied. The objective is to minimize makespan (Cmax) considering part family in the manufacturing cell flow line where the setup times are sequence dependent. Minimizing Cmax will result in the increment of output rate and the speed of manufacturing systems which is the main goal of such systems. This problem is solved using Ant Col...

Abstract This paper addresses a multi-objective energy-efficient scheduling problem of the distributed permutation flowshop with sequence-dependent setup time and no-wait constraints (EEDNWFSP), which have important practical applications. Two objectives minimization both makespan total energy consumption (TEC) are considered simultaneously. To address this problem, new mixed-integer linear pro...

Analysis of formal amino acid sequence identity between different TCRB chain (TCRB) hypervariable regions (CDR3) is commonly used to localize relevant sites of TCR antigen interaction or to yield indirect information on unknown corresponding antigens. However, this analysis sometimes fails to demonstrate expected concordances, e.g. between CDR3 from T cell clones of identical reactivity. Since ...
