MWHC2C

Description

This function obtains the associated costs in a model without holding costs and with two differents cost of product. Demands and capacities must be introduced in the order indicated by the ratios d/K. In other case, agents change their position.

Usage

mwhc2c(n=NA,a=NA,b=NA,d=NA,K=NA,c1=NA,c2=NA,cooperation=c(0,1),allocation=c(0,1))

Arguments

`n`	Agents in the inventory situation.
`a`	The fixed cost per order.
`b`	Vector. Shortage cost per unit to each agent.
`d`	Vector. Deterministic demands per time unit to each agent.
`K`	Vector. Warehouse's capacity to each agent.
`c1`	Value. Cost per unit of product from the first vendor.
`c2`	Value. Cost per unit of product from the second vendor.
`cooperation`	Option to indicate cooperation. If it exists `cooperation=1` else `cooperation=0`.
`allocation`	Option to indicate the allocation. If it is required `allocation=1` else `allocation=0`.

Value

A list with the following components:

"Optimal policies" A matrix with all possible coalitions in the first column. The second column contains the optimal order to each coalition. Last column indicates the global cost of this optimal order.
"GR-rule" A matrix, for each coalition (row), contains the coalition i(S) and allocations proposed by GR-rule.

Examples

mwhc2c(n=3,a=1,b=c(10,10,10),d=c(30,45,46),K=c(30,45,46),c1=3.5,c2=3,cooperation=1,allocation=1)
