heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...
The fragmentation and Segmentation of agricultural lands is one of the challenges facing rural development programs. Implementation of land consolidation policy in most parts of the Iran in the past years has always faced problems with farmers' participation and successful implementation of the project to solve this problem.

Current bioremediation techniques for petroleum-contaminated soils are designed to remove contaminants as quickly and efficiently as possible, but not necessarily with postremediation soil biological quality as a primary objective. To test a simple postbioremediation technique, we added earthworms (Eisenia fetida) or wheat (Triticum aestivum) straw to petroleum land-farm soil and measured biolo...
New panel data from India are used to examine the relationship between farm size and productivity based on a model incorporating agency costs favoring family workers, scaledependent returns to mechanization arising from the fact that a larger contiguous land area is better-suited for high-capacity machinery, and falling credit costs with owned land. The model provides guidance for imputing the ...
