  • Publication number: 20220215449
    Abstract: In a parts configuration plan generation device, a concretization processing unit (first concretization unit) concretizes an “abstract configuration” by using a first concretization pattern, and thereby generates a “base parts configuration”. A concretization processing unit (second concretization unit) applies a second concretization pattern to the base parts configuration and concretizes a parts item contained in the base parts configuration, and thereby generates a “candidate parts configuration”. An output unit outputs, as a “parts configuration plan”, the candidate parts configuration where concretization is done and satisfying a condition to be satisfied by a device to be built.

  • Publication number: 20220215312
    Abstract: In an equipment configuration plan generation device, an input unit receives an input value (request condition) of an entry regarding a request related to facility construction of a store and an input value (constraint condition) of an entry regarding a constraint condition related to the store. A concretization unit concretizes devices to be installed in the store in a step-by-step manner according to an input value of each entry regarding the constraint condition, and thereby generates an equipment configuration plan containing specific devices and satisfying the request (request condition).

  • Publication number: 20220089260
    Abstract: An outboard motor that controls combustion in an engine according to a purification rate by a catalyst and is capable of performing efficient engine combustion. The outboard motor includes a catalyst provided in an exhaust manifold of an engine and a second catalyst provided in an exhaust pipe, an air-fuel ratio sensor and an O2 sensor, which are located on an upstream side and a downstream side of the catalyst, respectively, and a controller for controlling combustion in the engine.
