STIcoo: STIcoo

Description

This function calculates the optimal number of orders and the associated cost 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 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.

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)
