Incorporating a Bayesian Network into Two-Stage Stochastic Programming for Blood Bank Location-Inventory Problem in Case of Disasters

Table 4

Decision variables.

	Symbol	Description
The; planning stage	xi	1 if blood bank candidate i is chosen, 0 otherwise.
	Ciab	Maximum inventory of blood product a with type b in blood bank candidate i (U)
	ssiab	Emergency stock of blood product a with type b in blood bank candidate i (U)
	shab	Emergency stock of blood product a with type b in hospital h (U)
The; operational stage		Supply quantity of blood product a with type b from donor point k to blood bank candidate i per period (U)
		Distribution flow of blood product a with type b from blood bank i to hospital h per period (U)
		Distribution flow of blood product a with type used to substitute type b from blood bank i to hospital h per period (U)
		Supply quantity of blood product a with type b from donor point k to blood bank candidate i under scenario s (U)
		Distribution flow of blood product a with type b from blood bank i to hospital h under scenario s (U)
		Distribution flow of blood product a with type used to substitute type b from blood bank i to hospital h under scenario s (U)
