The Captain’s Problem
The goal is to find the Arrival delay of the ship, a number of days varying from 0 to 6. This delay is the sum of two kinds of delay, the Departure delay and the Sailing delay. The Departure delay is the sum of three kind of delays, Loading, Maintenance and Forecast of bad weather. In this example, each delay is supposed to be of only one day for a maximum of three days. The Sailing delay can occur from bad Weather (one day) or Repairs at sea (one day each).
There are 8 variables involved: (Arrival delay, Departure delay, Sailing delay, Loading delay, Forecast of the weather, Maintenance delay, Weather at sea, Repairs at sea).
Six relations (R1 to R6) are defined between these variables.
Finally three inputs of evidence (L, F, M) are given.
Relations between the variables:
R1: ADS
A = D + S. \(Ω_A\) = {0,1,2,3,4,5,6}; \(Ω_D\) = {0,1,2,3}; \(Ω_S\) = {0,1,2,3}

## 3 frame 3 0.2The hypergraph of the Captain’s Problem
We now look at the Captain’s Problem as a belief network. The eight variables involved are the nodes of the graph: Arrival, Departure, Sailing, Loading, Forecast, Maintenance, Weather, Repairs. The edges (hyperedges) are given by the five relations R1 to R5 and the three inputs of evidence (L, F, M).
We use the package igraph 4 to produce a bipartite graph corresponding to the desired hypergraph.

Calculations to obtain the belief function of the Arrival delay using the peeling algorithm
Our goal is the calculation of the belief function of the variable of interest “Arrival”. We apply an algorithm called “Peeling” to the belief network. This is a process of successive elimination of variables (peeling) until only the variable of interest (Arrival here) remains. The elimination of a variable has the effect of integrating its contribution to the reduced graph, which is also called “message passing”.
Four parameters are necessary to trigger the algorithm. The first three are already defined when constructing the hypergraph. These are: captain_vars1: Variable numbers and size captain_rel_names: names of relations and evidences captain_hgm: Incidence matrix of the hypergraph
The fourth parameter is an order of elimination of the variables that
we have to set. here we set the elimination order to: 8 Repairs 4
