  Linear Programming (LP) models and technique among various mathematical optimization techniques have evolved through the years to optimize the crude blending and refining operations. The operations may include the crude evaluation, selection, scheduling and product logistics planning. The objective of this study was to develop a mathematical programming model for solving a blending problem in a major refinery in Alexandria, Egypt with the objective of maximizing Naphtha productivity. Refinery planning and optimization is basically addressed through special purpose linear programming software packages that remain a black box for the users and that are very costly for the organizations. The model developed in this work was proved to be highly effective at the level of solving the blending problem. This study has shown that the developed linear programming model for the blending problem has yielded better overall Naphtha productivity for the case of the oil refinery studied, as compared to results obtained by the commercial software.

  A field experiment was conducted at the Regional Agricultural Research Station of Barisal, Bangladesh during the Kharif season of the year 2000 to find the optimum fertilizer rate for summer mungbean cv. Barimung-4 in an attempt to maximize the yield potential. In this regard, various combinations of NPK fertilizers and Rhizobium inoculation (N20P40K20 kg ha–1, P40K20 kg ha–1, N20K20 kg ha–1, N20P40 kg ha–1, N20 kg ha–1, Rhizobium + P40K20 kg ha–1, Rhizobium, and control) were imposed to the experimental plots. Results revealed that Barimung-4 produced the maximum seed (1270.21 kg ha–1) and straw yields (2434.36 kg ha–1) when the crop was fertilized with N20P40K20 kg ha–1 followed by Rhizobium + P40K20 kg ha–1 (1220.30 and 2406.14 kg ha–1, respectively. The lowest seed and straw yields were obtained from the control (887.01 and 1864.68 kg ha–1, respectively). Different plant characteristics such as plant height, branches/plant, pods/plant, pod length, seeds/pod, 1000-seed weight and harvest index increased significantly due to the application of various combinations of NPK fertilizers and Rhizobium inoculation over the control.
