Description

Generic function for showing the allocations proposed by SOC rule under a EOQ or EPQ model.

Usage

SOC(n = NA, a = NA, d = NA, h = NA, m = NA, r = NA, s = NA, 
model = c("EOQ", "EPQ"), cooperation = c(0, 1))

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.

s

Vector. Cost of a shortage to each agent.

model

Model to select. EOQ and EPQ models can be considered.

cooperation

Option to indicate cooperation. If it exists cooperation=1 else cooperation=0.

Value

Matrix with number of rows equal to the number of coalitions and n columns. For each coalition or row, the output shows the cost that SOC rule allocates to each player or column.

Examples

SOC(n=3,a=600,d=c(500,300,400),h=c(9.6,11,10),m=NA,r=NA,s=NA,model="EOQ",
cooperation=0)
