To control a production-inventory system, a manager has to consider the variability in demand as well as variability in her production process. Both types of variability corrupt system performance and by alleviating either of them, the manager can improve the performance of the system. There has been a recent trend towards investing in better information systems to provide better advance demand...

In animal production there are two core dimensions to environmental fit, one that centres on the capacity of the environment to meet an animal's needs and the other concerns the capacity of the animal to match or 'fit' the environment. Efforts to increase capacity in both of these dimensions can contribute substantially to the continuous improvement of animal welfare within different livestock ...

Manufacturers have two general strategies to guard against uncertainties in the production or demand process: (a) building inventory to hedge against periods in which the production capacity is not suÆcient to satisfy demand, and (b) temporarily increasing the production capacity, for example, by hiring temporary workers, adding overtime and/or extra shifts, or outsourcing part of the productio...

We investigate a firm’s product line design, and capacity investment problem for vertically differentiated products along design quality levels. Customers arrive according to a Poisson process and are heterogeneous in their marginal valuation of the quality level. Customers make product choices to maximize a linear utility function of price, quality level, and waiting cost. Resulting product de...

This paper presents two polynomial time algorithms for the constant capacitated lot sizing problem with a batch production. We give several optimality properties for the general problem. Assuming constant production capacity, constant batch size and WagnerWhitin cost structure, we derive O(T 4) and O(T 6) time algorithms respectively for the case with production capacity multiple of the batch s...

Capacity dimensioning in production systems is an important task within strategic and tactical production planning which impacts system cost and performance. Traditionally capacity demand at each worksystem is determined from standard operating processes and estimated production flow rates, accounting for a desired level of utilization or required throughput times. However, for distributed prod...

Capacity coordination, as the tactical level of hierarchical production planning in hybrid MTS/MTO systems, includes numerous important decisions. In this paper, two of these decisions i.e. finding the best strategy for the acceptance/rejection of incoming orders and determining orders’ due dates – are investigated. Also a simulation model is proposed to evaluate the efficiency of the presented...

Theoretically we understand the dimensions of both generic and specific adaptive capacity, however, there are few studies which document actual observed adaptive capacity. This study aims to address this gap by documenting the adaptive capacity of Indian rice production systems, an agrosocio-ecological system. We explore how Indian rice production systems have responded to historical climate sh...
