Determining the most vital link in a flow network

The most vital link in a single commodity flow network is that are whose removal results in the greatest reduction in the value of the maximal flow in the network between a source node and a sink node. This paper develops an iterative labeling algorithm to determine the most vital link in the network. A necessary condition for an are to be the most vital link is established and is employed to decrease the number of ares which must be considered.     

Multiproduct lot-size scheduling with proportional product demands

In this paper we consider the multiproduct, multiperiod production-scheduling model of Manne under the assumption that, across products, demands are interrelated over time. When demand requirements are proportional we show that the solution has a specific structure determined by the ratio of setup to production-run time of each product. This structure holds for any length horizon and may permit a substantial (time) savings for column generation solution procedures.     

Statistical quality control of information

This paper was written to promote interest by management and statistical quality control personnel in the current need for statistical quality control of information of all types. By way of illustration, a step by step procedure for implementing such control on computer files is presented. Emphasis has been placed on the sequencing of the system rather than the underlying techniques.     

Soldiers,the Frontier and the Politics of Command in British India

The defence of India in general and the North West Frontier in particular was central to strategic debate within the late Victorian army, creating one of the fault lines between rival factions competing for key commands and appointments. After a discussion of the varying strategic options debated within the British and Indian armies, the article examines the impact of Indian defence upon the ‘politics of command’ with particular reference to the appointment of Commanders-in-Chief in India between 1876 and 1892.
