Tang In this paper, we consider two new types of the two-machine flowshop scheduling problems where a batching machine is followed by a single machine. The first type is that normal jobs with transportation between machin...

A pricing factor plays a dominant role in consumer behavior most countries affected by the COVID19 pandemic. People have lost their job while others renegotiated for low-paying jobs during this Thus, article aims to develop viable model consider various aspects of Here, we an optimal ordering quantity inventory deteriorating items, which are still demand depending upon selling price product. Th...

In the last decades, availability constraint as well learning and deteriorating effects were introduced into production scheduling theory to simulate real-world case studies overcome limitation of classical models. To best our knowledge, this paper is first in literature address permutation flowshop problem (PFSP) with flexible maintenance under deterioration minimize makespan. Firstly, we PFSP...

 This paper introduces the effects of job deterioration and sequence dependent set- up time in a single machine scheduling problem. The considered optimization criterion is the minimization of the makespan (Cmax). For this purpose, after formulating the mathematical model, genetic and tabu search algorithms were developed for the problem. Since population diversity is a very important issue in ...

Analysts and economists often face the task of using employment metrics to characterize industries interest. Some key challenges can be understanding where find metrics, differences in various when each metric should used. This article analyzes a variety publicly available data for United States compares these data. A detailed description intricacies source is provided, which covers factors suc...

This paper investigates the problem of just-in-time permutation flow shop scheduling with limited buffers and linear job deterioration in an uncertain environment. The fuzzy set theory is applied to describe this situation. A novel mixed-integer nonlinear program is presented to minimize the weighted sum of fuzzy earliness and tardiness penalties. Due to the computational complexities, the prop...

emobility challenges of the developingworld are considerably different than those inwealthier, advanced countries, and so are the challenges of coordinating transportation and land use. Rapid population growth, poverty and income disparities, overcrowded urban cores, poorly designed road networks, spatial mismatches between housing and jobs, deteriorating environmental conditions, and economic...

We show that the linear objective function of a search problem can be generalized to a power function and/or a logarithmic function and still be minimized by an index priority rule. We prove our result by solving the differential equation resulting from the required invariance condition, therefore, we also prove that any other generalization of this linear objective function will not lead to an...
