One-Dimensional Space Allocation: An Ordering Algorithm
Operations Research, 1969The space-allocation problem arises when an architect tries to arrange rooms of fixed area but unspecified shape on a floor plan in such a way as to minimize a given linear combination of the distances between all pairs of rooms. In one dimension, this is the problem of ordering line segments along a simple axis or rooms along one side of a corridor ...

Wafer-to-Order Allocation in Semiconductor Back-End Production
2019 Winter Simulation Conference (WSC), 2019This paper discusses the development of an efficient algorithm that minimizes overproduction in the allocation of wafers to customer orders prior to assembly at a semiconductor production facility. This study is motivated by and tested at Nexperia’s assembly and test facilities, but its potential applications extend to many manufacturers in the ...

Efficient allocation of online grocery orders
International Journal of Productivity and Quality Management, 2006Despite some initial setbacks, the online grocery business is viable and growing. In this paper, we discuss the industry's value proposition, its business models, the various quality issues faced by an e-grocer and the trade-offs faced in the selection of a highly efficient fulfilment strategy.

Phase Ordering of Register Allocation and Instruction Scheduling
1992Register allocation and instruction scheduling are often separated due to the complexity of each. But if register allocation is performed before scheduling, it may introduce artificial data precedence, keeping the instruction scheduler from doing its best job.

Order allocation in a multiple-supplier environment
International Journal of Production Economics, 2005Abstract The objective of this article is to study the effects of an order allocation procedure in a supply chain. This supply chain consists of a company that can order products from multiple suppliers. At any time of an order, decisions have to be made by the company concerning the allocation of products to the suppliers and the respective order ...

Memory allocation and higher-order functions
Papers of the Symposium on Interpreters and interpretive techniques - SIGPLAN '87, 1987This paper presents a constant-time marking-collecting algorithm to efficiently implement recursion with a general heap memory rather than with a vectorial stack, in a context of frequent captures of continuations. It has been seen to reduce the 80% garbage collection overhead to less than 5% on average.The algorithm has been built into a ...

An Ordered LDPC Coded OFDM System with Power Allocation
2007 IEEE Wireless Communications and Networking Conference, 2007A novel adaptive LDPC coded OFDM transmission technique is proposed in this paper. Assuming the channel state information (CSI) is known to the transmitter, the irregular LDPC coded bits are ordered and allocated into subcarriers adaptively. Then two power allocation schemes, fixed ratio truncating (FRT) and fixed ratio inverse water-filling (FRIWF ...

Order Statistics and Optimal Allocation Problems
1991Abstract : Order statistics play an important role reliability. The life time of any coherent system is the first order statistic of the, generally dependent, lives of its cut sets. For the important class of k-out-of-n systems, the lifetime of the system is the n-k + 1th order statistic of the lives of its components, which are often assumed to be ...

Allocation of Order Quantity Among Suppliers
Journal of Purchasing and Materials Management, 1989This article presents a linear programming model that can be used in the simultaneous determination of the number of suppliers to utilize and the purchase quantity allocations among suppliers in a multiple sourcing system. The model is simple and powerful. It can be used to make rational multiple sourcing decisions.
