We consider processing and shipment scheduling of a batch of size M jobs on a flexible (multifunctional) machine. All jobs in the batch require the same sequence of N operations on the machine. Costs are incurred in the forms of holding costs of jobs waiting for the next operation, setup costs whenever the machine is set up for a new operation, and shipment cost whenever the whole batch or a pa...

CO2 emissions from maritime transport operations represent a substantial part of the total greenhouse gas emission. Vessels are designed with better energy efficiency. Minimizing CO2 emission in maritime operations plays an important role in supply chain decarbonisation. This paper reviews the initiatives on slow steaming operations towards the reduction of carbon emission. It investigates the ...

In this chapter, we present a procedure that seeks the global minimum for the capacitated Euclidean location-allocation problem which is defined as follows. Given the fixed location of m existing facilities or customers on a continuous plane and their associated demands, we wish to determine the location of n new facilities or sources with known capacities, and the allocation of its supply, in ...

stallions diluted at a ratio of 3:1 (extender: semen) with a commercially available stallion semen extender (Exodus Breeders Supply, York, PA) and packaged into each of the containers. Three sets of containers per season (winter and summer) where commercially shipped from Tucson, AZ to Springfield, MO with overnight delivery. Spermatozoal motilities were evaluated utilizing CASA following shipm...

Abstract In this paper, we study a stochastic single-item, single-stage inventory system, in which orders from several production facilities are placed at one warehouse. An ( R , Q ) policy is applied to control the warehouse, and arrive according Poisson process include due date such that some information about future demand available. This advance (ADI) can be used adapt time-based shipment c...

This paper addresses a practical application of an order-based genetic algorithm (GA [1, 2, 3]) to a realworld shipment scheduling problem for a major ore-mining company. The problem itself is described in detail in section 1, followed by a thorough discussion of the algorithm employed, including chromosome representation, decoding and evaluation, as well as all of the genetic operators used.
