STI {Inventorymodel}

STI

Description

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

Usage

STI(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

This function calculates two vectors. The first one shows the optimal order for each agent. The second vector indicates the associated cost to these orders.

Examples

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