Creating a New Scenario

anyLogistix scenario stores the data about your supply chain configuration. You can conduct experiments of various types for the created scenario to solve different business tasks.

Each project starts with creating a scenario and populating it with data. Scenario contains complete information on shipping and related operations, as well as all the data on vehicles, warehouses etc. This data is used for running experiments and building reports.

To create a scenario

  1. You can create a new scenario by doing either of the following:

    • Choose New Scenario from the File menu
    • Click the New Scenario button in the project tree toolbar.
    • Press Ctrl + N

    The Scenario Properties dialog box will open:

  2. Define the basic parameters of your scenario. For more information refer here.
  3. If required, click Add scenario data to open the advanced section containing scenario settings with editable predefined data.

  4. Provide the required values for the corresponding parameters. For more information refer here.

  5. Click OK. The new scenario will be instantly opened. You can always modify the scenario properties later by right-clicking the scenario in the Project tree and selecting Properties from the context menu. All the currently opened scenarios are available in the corresponding scenario type tab.

    The error messages may pop-up if:
    • The Number of sites prevails over the Number of locations.
    • The selected countries (or a group of countries) has less locations than you specified in the Number of sites parameter (a location in this case is a city with a minimum population of 15000 citizens).

The New scenario dialog parameters

  • Scenario name – the name of the scenario that will be displayed in the Project tree.
  • Scenario type - sets the experiment type for the scenario that you are creating. The newly created scenario will be available in the tab referring to the specified experiment type:
    • Greenfield Analysis (GFA) - finds optimal locations for the supply chain sites.
    • Network Optimization (NO) - finds exact locations and forms sourcing policies.
    • Simulation (SIM) - models the actual products delivery on the GIS map with detailed statistics generated in real-time.
    • Transportation Optimization (TO) - optimizes the cost of delivering products from a site to the customers it services

      The list of tables differs for each experiment type.

  • Created by – displays the name of the current user (not editable);
  • Creation date – displays the current date (not editable);
  • Default access – defines access permissions for other users (can be later changed if needed):
    • None - scenario is not visible to other users.
    • View - users are not allowed to edit the scenario.
    • Edit - users can edit this scenario.
    • Full - users have full access to the scenario data.
  • Start date – [Defined in the Periods table] scenario starting date and time. It is used for data sampling, and defining simulation experiment starting date;
  • End date – [Defined in the Periods table] scenario ending date and time. It is used to define simulation experiment ending date;
  • Description – optional field. You can add a comment to the scenario.
  • Add scenario data - opens advanced section containing scenario settings with editable predefined data.

Advanced parameters of the New scenario dialog

  • Please select data generation type:
    • One customer per location with demand proportional to population density - distributes demand within the location(s) of the country/countries according to their population density.

      Demand in this case is calculated as population * order size per citizen for the specified period of time, where:

      • Population - equals the specified Number of locations, since we have one customer per location. (e.g. 100 locations = 100 customers)
      • Order size per citizen - the specified demand of the supply chain per each citizen of the specified number of locations.
      • Period of time - the time period during which the quantity of products (specified in the Order size per citizen) is ordered (periodic type of demand).
    • Having equal demand, customers are distributed by population density - the specified number of customers is distributed within the specified number of locations according to their population density.

      Demand in this case is calculated for each location as order size per customer for the specified period of time, where:

      • Period of time - the time period during which the quantity of products (specified in the Order size per customer) is ordered (periodic type of demand).
      • order size per customer - the demand of the supply chain per each customer (customers are defined in the Total number of customers)

      The number of customers for each location is calculated as Max number of locations * k, where:

      • Max number of locations - the specified number of locations (cities) the supply chain must have.
      • k - the ratio of the location's population to the total sum of population in the specified Number of locations up to.

        The resulting amount of customers is rounded up to constitute an integer.

    • Having equal demand, customers are uniformly distributed by locations - the specified number of customers is evenly distributed within the specified number of locations.

      Demand in this case is calculated for each location as order size per customer for the specified period of time, where:

      • Period of time - the time period (periodic type of demand) during which the quantity of products (specified in the order size per customer) is ordered.
      • order size per customer - the demand of the supply chain per each customer (customers are defined in the Number of customers per location)

      The number of customers for each location is calculated as Number of customers per location * Max number of locations

  • Select country/countries - specify a country or a group of countries that must be involved in this supply chain.
  • Create country groups for customers - [Disabled by default] enable to group customers by their location. New group(s) will be created (in the Groups table) for each country specified in the Select country/countries option.

    The number of groups may be less than the number of specified countries due to significant difference in population size.

  • Number of locations - specify the number of locations (cities) to create within the specified country/countries (anyLogistix always chooses locations (cities) with the highest population).

    The actual number of locations (cities) in a scenario might be less than expected, since anyLogistix considers cities only with population of 15 000 citizens or more.

  • Number of locations up to - [Available if Having equal demand customers are distributed by population density is selected] specify the maximum number of locations (cities) to create within the specified country/countries (anyLogistix always chooses locations (cities) with the highest population).

    The number of locations that will be created in the scenario may be equal or less than the specified max number. This may happen because population of cities in the specified countries might differ drastically and the resulting number of customers for a particular location might constitute a decimal, which will be rounded up to constitute an integer, thus increasing the number of customers in this particular location and decreasing the overall number of the remaining customers. As a result there might be no customers left for the last (or several) locations. These locations will not be created and the overall number of locations in the scenario will be decreased to the ones with customers.

  • Number of customers per location - [Not available if Having equal demand, customers are distributed by population density is selected] specify the number of customers to place at each location within the specified country/countries.
  • Total number of customers - [Available if Having equal demand, customers are distributed by population density is selected] specify the number of customers the supply chain must contain.
  • Order placement frequency (period), days - specify the number of days in periodic type of demand.
  • Demand per citizen per period - [Available if One customer per location with demand proportional to population density is selected] the demand of the supply chain per each citizen of the specified number of locations.
  • Demand per customer per period - [Not available if One customer per location with demand proportional to population density is selected] the demand of the supply chain per each customer of the supply chain.
  • Number of products - specify the number of products types to create for this supply chain.

    If you specify 2 or more products here, then a new Generated products group will be created in the Product Groups table. This group will be used by default in the Demand table.

  • Number of sites - [Not available for GFA scenario type] specify the number of sites this supply chain must contain.
  • Site opening cost - [Not available for GFA scenario type] specify the cost of opening a site.
  • Site carrying cost - [Not available for GFA scenario type] specify the cost of storing products at a site.
