This study proposes to use the channels having horizontal bottom and parabolic sides (HBPS) as substitute for trapezoidal channels. The acceptability of HBPS channel is contested by using the criteria of minimization of cost and flooding probability. An optimization model is developed to...

While an item substitution measure provides for the direction, demand transference quantifies the magnitude of demand that may get transferred to an item a) When its substitute is deleted b) When it is introduced in a store and cannibalizes on similar items. This, hence, is an important input...
