The difference between the smallest unused cost and the next smallest unused cost.
The transportation problem with overabundance add up to demand and differing punishment costs for not taking care of the individual demands is changed over to a standard transportation problem.
The fixed charge transportation problem (FCTP) is an expansion of the exemplary transportation problem in which a fixed cost is caused for each supply point that is utilized as a part of the arrangement. A branch and bound strategy which requires the utilization of two subproblems (an exemplary transportation problem and a backpack problem) can be utilized to understand the FCTP. Dissimilar to fixed change problems, with the FCTP, there is a many-to-one correspondence between the persistent factors of the transportation problem and the fixed charge factors of the backpack problem.
