Please solve the above exercise by using Ships as logistics
connection between two production sites: The ships will be chartered for a whole year, so it is necessary to maxime their use coefficients; all the ship have the same capacity (size). Both Loading and Unloading times are based on the same Port Loading/Unloading speed. The Mooring time include all the nautical activities and times related to entering or exiting from each port. The A and B port have just a single dock position available, so in case of other ship in loading/unloading operations it is required to wait. Hypotheses about STD (Standard Deviation) are provided on the variables affected by stochastic phenomena; it is requested to identify both the solution for the deterministic case (in this case please consider all STD equal to zero) and the solution to the stochastics problem (considering STD as proposed in the bottom of the applet). The daily ship cost is based on the following relation: Ship Daily Cost = Ship Basic Cost + Ship Table Cost (based on its capacity) The exercise requires to introduce in the textbox the following values:
Based on the results provided the student will receive a grade [0 bad - 30 excellent] for deterministic and stochastic solutions. Please note that you can RESET the exercise in order to have a new problem. The RUN button enable the evaluation of the exercise, after this is pushed for the first time the grade cannot be changed in the same problem. All the problems have an ID Code It is possible to define the simulation duration (it is recommended 365 days) as well as the period for refreshing (1.0 day recommended). |
