Other studies focused on addressing inventory in regional blood banks, focused on optimising the number of daily collections. But it also clarified that determining the optimal size of total units to be collected (overall eight blood types) to meet demand in time is a complex process. Therefore, an exact solution to this problem is impractical to obtain (Prastacos 1984).
In this paper, we developed a linear programming model of inventory management at a regional blood bank. The model explained within the following section is focused on offering a rather simplified linear model to meet daily demand and supply.
