STIcoo {Inventorymodel}

STIcoo

Description

This function obtains the optimal orders and the associated cost when agents are cooperating in the inventory transportation system when agents are cooperating.

Usage

STIcoo(n = NA, a = NA, av = NA, d = NA, h = NA, m = NA)

Arguments

n

Agents in the inventory situation.

a

The fixed cost per order.

av

Vector. The transportations cost per order to each agent.

d

Vector. Deterministic demands per time unit to each agent.

h

Vector. Holding cost per time unit to each agent.

m

Vector. Number of orders to each agent (optional).

Value

A list with the following components:

• Optimal order If n is lesser than 0, a matrix with all possible coalitions in the first column. The next n columns contain the associated cost to each agent in the coalition. Last column indicates the global cost of the optimal order. Otherwise, this matriz contains the individual costs and the associated values for N.

Examples

STIcoo(n=3,a=200,av=c(300,300,900),d=c(90,80,20),h=c(0.06,0.06,0.1),m=NA)
