In this paper, power limited relay network is considered. We take one example of the limited relay, i.e. energy harvesting (EH) relay to study the power planning problem. It is assumed that the EH process is stationary and periodical. A twoEH-relay network is considered for simplicity. Efficient power planning can maximize the sum capacity that can be achieved by the saved power of EH relays. S...

BACKGROUND Chemical exposure is a major health problem globally. Poison control centers (PCCs) play a leading role both in developed and developing countries in the prevention and control of poisonous chemical exposures. In this study, we aimed to assess the current state of PCCs in Pakistan and highlight capacity building needs in these centers. METHODS A cross-sectional survey of the two re...

Planning horizon is a key issue in production planning. Different from previous approaches based on Markov Decision Processes, we study the planning horizon of capacity planning problems within the framework of stochastic programming. We first consider an infinite horizon stochastic capacity planning model involving a single resource, linear cost structure, and discrete distributions for genera...

The administration of high doses of therapeutic antibodies requires large-scale, efficient, cost effective manufacturing processes. An understanding of how the industry is using its available production capacity is important for production planning, and facility expansion analysis. Inaccurate production planning for therapeutic antibodies can have serious financial ramifications. In the recent ...

Vietnam has been decentralizing nutrition planning to provinces, which could help with local relevance and accountability. Assessment in 2009 found a continuing top-down approach, limited human capacity, and difficulty in integrating multiple sectors. Alive and Thrive (A&T) provided targeted assistance and capacity-building for 15 provincial plans for nutrition (PPNs). We aimed to (i) assess PP...

The scale planning of the coal logistics center plays an important role in coal logistics network planning. Based on the coal logistics network planning, this paper analyses the coalmine production capacity, transportation capacity, coal demand and other factors, then brings forward the demand trend coefficient on that basis. Further, the authors construct a scale-planning model for the coal lo...

The strategic capacity planning function must be a core competency for firms in capitalintensive, long equipment lead-time industries such as the semiconductor industry. Major investment decisions are made years in advance of forecasted demand, and involve a complex array of product design and manufacturing parameters. The high stakes and breadth of uncertainty require a well-orchestrated, comp...

Forest and colleagues have persuasively made the case that policy capacity is a fundamental prerequisite to health reform. They offer a comprehensive life-cycle definition of policy capacity and stress that it involves much more than problem identification and option development. I would like to offer a Canadian perspective. If we define health reform as re-orienting the health system from acut...

We provide a structured overview of the typical decisions to be made in resource capacity planning and control in health care, and a review of relevant OR/MS articles for each planning decision. The contribution of this paper is twofold. First, to position the planning decisions, a taxonomy is presented. This taxonomy provides health care managers and OR/MS researchers with a method to identify...

This paper investigates a capacity planning strategy that collects commitments to purchase before the capacity decision and uses the acquired advance sales information to decide on the capacity. In particular, we study a profit-maximization model in which a manufacturer collects advance sales information periodically prior to the regular sales season for a capacity decision. Customer demand is ...
