In the flow shop delivery time problem, a set of jobs has to be processed onmmachines. Every machine has to process each one of the jobs, and every job has the same routing through the machines. The objective is to determine a sequence of the jobs on the machines so as to minimize maximum delivery completion time over all the jobs, where the delivery completion time of a job is the sum of its c...

background and objective: preterm birth occurs in 8% to 11% of all pregnancies and is responsible for 75% to 80% of all neonatal deaths. cytokines may be involved in the etiology of preterm birth through their stimulation of prostaglandin synthesis. cytokines may be released intocervicovaginal fluid during the breakdown of the chorio-decidual adhesion or from an inflammatory reaction in the sam...

Design/bid/build and design/build are two principal project delivery systems used worldwide. The performance of each project may differ with the type of procurement system used. This study has two aims: firstly, to assess and compare the performance of design/bid/build and design/build projects in Lebanon; secondly, to compare the results with the performance of equivalent systems in the Far Ea...

background: cesarean section delivery can lead to much maternal morbidity. different cytokines have been reported to be influenced by the mode of delivery. objective: to investigate the influence of mode of delivery on maternal, placental and cord sera of interferon gamma (ifn-γ), interleukin-4 (il-4) and interleukin-10 (il-10) levels. methods: these three cytokines were measured using elisa in...

This paper addresses a production and outbound distribution scheduling problem in which a set of jobs have to be process on a single machine for delivery to customers or to other machines for further processing. We assume that there is a sufficient number of vehicles and the delivery costs is independent of batch size but it is dependent on each trip. In this paper, we present an Artificial Imm...
