Production Planning at Winstone Aggregates, Including Competitors
نویسنده
چکیده
The Auckland aggregate market is estimated to be 7.2 million tonnes a year. Sixteen major quarries supply this market. Because of the number of suppliers and the variety of products, planning in this complex environment is difficult. Winstone Aggregates is the largest producer of rock products in Auckland. It owns nine quarries and supplies slightly more then half of the region's aggregate needs. This paper describes a model of the Auckland aggregate market developed as a decision making tool for Winstone Aggregates. It also describes some of the methods used to collect information for the model. A Windows interface was developed to make the model easy to use.

Bayesian Speech Production: Evidence from Latency and Hyperarticulation
Both response latency and phonetic variation reflect competition among alternatives during the speech production process. A review of the literature finds an apparent contradiction in the latency results. In some tasks where latency is measured, similarity between targets and competitors results in slower reaction times. In other tasks, similar competitors appear to facilitate production times ...

متن کاملHierarchical Approach for Production Planning and Scheduling under Uncertainty
In this paper, production planning and scheduling problems are addressed through a hierarchical framework. The planning problem aggregates orders in the planning period and considers uncertainty utilizing a multi-stage stochastic programming formulation where three stages are considered with increasing level of uncertainty. The planning model includes material balances and time horizon constrai...
