A Fuzzy Multi-Objective Mathematical Model for Supplier Evaluation in a Reliable Supply Chain considering Different Risk Levels

Table 3

The notation of the proposed mathematical model.

	The weight of goal j
	Negative deviation from goal j
	Positive deviation from goal j
	The defined level of goal j
A	The weighted sum of deviations from goals
	Penalty for non-compliant production of suppliers
	Delivery schedule penalty
	Technical coefficients
	Maximum (minimum) value of the goal j
	Price of raw materials supplier i
	The cost of transporting the product of the supplier i
	Supplier i capacity
	Total company demand (under uncertainty)
	Timely delivery point of supplier i
	After-sales service of supplier i
	Level of flexibility in improving the quality of the supplier i
	Order quantity from supplier i
