Question (4) As an Operations Research Analyst, you are tasked with optimizing the shipping schedule for a transportation problem involving four supply sources ($1, $2, $3, $4) and four demand destinations "DI, D2. D3. D4). The transportation cost per unit from each source to each destination is given in the cost matrix below. The supply availability at cach source and the demand requirement at each destination are also provided: DI D2 D3 D4 ST 10 9 425 14 $2 16 14 20 450 6 15 18 17 500 1 1 8 12 SA O 50 375 375 500 175 Problem Requirements: 1. Determine the initial feasible solution using the Least Cost Method (LCM) 2. Calculate the total transportation cost (TC) for the LCM solution 3. Assess the optimality of the solution using the MODI (Modified Distribution) Method Apply the U-V multiplier method (Steppingstone approach) to evaluate if the cur solution is optimal. 4. Discuss the implications of transportation optimization on logistics efficiency, supp chain cost reduction, and resource allocation
