This paper addresses the problem of batch scheduling in an unrelated parallel machine environment with sequence dependent setup times and an objective of minimizing the total weighted mean completion time. The jobs' processing times and setup times are stochastic for better depiction of the real world. This is a NP-hard problem and in this paper, new heuristics are developed and compared to existing ones using simulation. The results and analysis obtained from the computational experiments proved the superiority of the proposed algorithm PMWP over the other algorithms presented.

Border Security is a complex system consisting of many interrelated components that must function as a whole in order to be effective. The efficacy of border security is dependent on several independent agencies; these include U.S. Customs and Border Patrol (CBP), Immigration and Customs Enforcement (ICE), the Department of Justice (DOJ), state and local law enforcement, and many others. Border security is not only a function of how well each of the agencies perform individually but also how well they interact to accomplish a goal. This paper attempts to model border security from a Border Patrol (BP) perspective using discrete …
