During the 1980s various approaches to batch-type manufacturing environments were implemented. The most popular of these were MaterialRequirements Planning (MRP), ('JfOUP Technology (GT) and Just-In-Time (JIT). However few successful implementations of any of these approaches were achieved [1] [2] [3]. This paper compares the various approaches of GT, MRP, TIT along with the integrated approach...

The deficiencies in previous quantitative models for buyer–supplier coordination in a just-in-time (JIT) environment are corrected. An expanded model incorporating additional factors is developed and the factors are ranked through a detailed numerical analysis. Factor ranks are then compared with results of a series of semi-formal interviews with supplier and purchasing representatives. Publish...

Among the rare bone tumors, the osteoblastoma is a fascinating tumor. The rarity, the predisposition to occur in any bone and the diagnostic dilemma makes this infrequent tumor interesting. It is sporadically reported in the literature and what is rarer is its occurrence in the pelvis. The unusual location and inconclusive radiographic findings with diffused diagnostic evidences delays the mana...

The genus Silene includes 98 species in Iran, with 35 endemic to the Iranian plateau (26 species for Iran). The Iranian species are placed in 21 sections. In this article, the most important characteristics for the separation of the sections, relationships between the sections, and an identification key for the sections in Iran are presented. For each section a distribution map is provided. The...

This study examines the relation between a static and a dynamic measure of interaural correlation discrimination: (1) the just noticeable difference (JND) in interaural correlation and (2) the minimum detectable duration of a fixed interaural correlation change embedded within a single noise-burst of a given reference correlation. For the first task, JNDs were obtained from reference interaural...

This paper addresses the issue of combining qualitative and quantitative methodologies in management and organization research. It reviews the extant literature, and applies such combined methodology in a research project on vertical strategic alliances, conducted within a just in time manufacturing environment in North America, in 2001. While the major positive and negative aspects are highlig...

We describe two pilot studies of code review by and for scientists. Our principal findings are that scientists are enthusiastic, but need to be shown code review in action, and that just-in-time review of small code changes is more likely to succeed than large-scale end-of-work reviews.
