The model leather products manufacturing factory of leather industry development institute (LIDI) suffers from poor performances due to various problems. The purpose of this study is, therefore, to improve the performance of the case company using scheduling techniques. Proper scheduling technique can result in dramatic improvements in layout, utilization, idle time, make span and tardiness reduction. The existing company performance and various another scenarios were analyzed by using different sequencing rules plus Johnson’s and Campbell’s algorithms. The analysis and discussion showed that the feasible scheduling was of flow shop and while product layout was seen most preferable that result in reduction of machine idle time & make span by 3.00 & 4.33 hours respectively. Total flow time was reduced by 82.9% and machine utilization was improved by 16.15% when compared with existing layout. Through production lines 1 or 2 of scenario-2 with the sequence of J1, J2, J3, J4 and J5, the company should make possible arrangements for such improvements. © Springer International Publishing Switzerland 2015.
