Inventorymodel (version 1.1.0.1)

EPQ: EPQ

Description

This function obtains the optimal orders and the associated cost in the EPQ model.

Usage

EPQ(n = NA, a = NA, d = NA, h = NA, m = NA, r = NA, b = NA)

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.

Arguments

n

Number of agents in the inventory model.

a

The fixed cost per order.

d

Vector. Deterministic demands per time unit to each agent.

h

Vector. Holding costs to each agent.

m

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

r

Vector. Replacement rate to each agent. In general, r>d.

b

Vector. Cost of a shortage to each agent.

Examples

EPQ(n=3,a=600,d=c(500,300,400),h=c(9.6,11,10),m=NA,r=rep(600,3),b=c(100,150,200))
