1. Current version
    1. Capacity supply
      1. Workcentres
        1. Grouped by Macola departments
        2. Workcetres are created in VP but could be mapped to existing in macola
        3. Do not use Macola capacity
        4. Do not have SFC workers or machines assigned; qty of empl specified for POP only
        5. finite (one job at a time) and infinite (multiple jobs at a time) types
      2. Calendars
        1. Created in visual planner
        2. Do not synchronized with Macola calendars
        3. Cover one week (7 days for 24 hours)
        4. One workcentre is covered by one calendar with possibility to be edited by Cal.Day rules
      3. Capacity supply meaning
        1. Capacity means working hours time value specified by calendar on workcetre it is assigned to in specified time interval
        2. finite type:if job covers some capacity time interval that means capacity is fully used in it
        3. Infinite type: Capacity time interval has infinite hours
    2. Resource demand
      1. POP
        1. POP demand maintenance created in VP, no influence from Macola
        2. POP demand is calculated and as relation of qty of items to produce to productivity of an item on WC
        3. Productivity of item may dynamically change depending from qty of empl specified on WC cal.day rule.
        4. Productivity is specified as relation of Items qty that may be produced in specified WC in one hour of capacity. Productivity is maintained in VP
      2. SFC
        1. SFC demand means demand of SFC operation(s) in hours
        2. SFC demand value is presented as nos of hours needed to fulfill operation on WC. Hours aren't distinguished between workers and machines
        3. SFC demand data is fully taken from Macola SFO operation routing (Item primary routing in case of MRP or W-IFF)
        4. SFC Demand Value is calculated based on Routing values: WC load code, standard qty of empl and machines; std empl hours , std machines hours
        5. SFC demand value is presented in hours per operation execution
    3. Scheduler logic
      1. POP
      2. SFC
        1. SFC demand does not depend from Macola Workcentre level. Macola WC values like efficiency or labor factor do not take place. Macola capacity isnt influence as well
        2. SFC demand is placed against VP macola capacity, demand hour covers capacity hour in finite type and infinirte hours available in infinite type
        3. VP alternative WC may be used instead of original WC specified in operation. Demand still remains as it was on original wc
  2. Proposed version
    1. Capacity supply
      1. Workcentres
      2. Calendars
    2. Resource demand
      1. POP
      2. SFC
    3. Scheduler logic
