Abstract: As a plurality of resource types relating to production, there are two or more resource types including Money from among resource types of Man, Machine, Material, and Money. Execcution past record information indicates, for each of one or more resource types other than Money and for each resource belonging to the resource type, a step performed on the resource and an execution time block of the step. Expense information indicates, for at least one of the above-mentioned one or more resource types and for each resource belonging to the resource type, an expense relating to the resource. The system displays a cost chart based on the result of the cost calculation process. The cost chart shows costs in management unit same as or different from those of the steps, and has a time axis and a management unit axis (axis perpendicular to the time axis).

Abstract: Regardless of the production method applied, it is possible for a user to estimate a factor that causes trouble in one of the resources belonging to a resource type. A supporting system refers to management information indicating a production past record of the production system, and displays an overlay chart in which a diagram chart is relatively superimposed on a Gantt chart. The Gantt chart is a chart for a first resource type and has a resource axis and a time axis. The diagram chart is for a second resource type. In the overlay chart, a polygonal line connecting a plurality of points corresponding to a second resource, belonging to the second resource type, is on the Gantt chart, and each point is plotted at a position corresponding to an execution time of a step and a first resource, belonging to the first resource type, related to the step.

Abstract: Production past record information showing the execution time point of each step is accumulated for each product loaded in a production system. A supporting system calculates, for each step, a retention increase rate at each time point on the basis of the production past record information. The “retention increase rate” is an amount of increase in retention number per unit time. The supporting system displays a holistic chart for a production situation, which has a time axis and a step axis (axis perpendicular to the time axis and corresponding to steps). A display mode of each position in the holistic chart depends on whether a retention increase rate for the time point and step corresponding to the position is a negative value, zero, or a positive value, and a difference between the retention increase rate and a rate reference value (a reference value for the retention increase rate).

Abstract: The production management support system analyzes, on the basis of one or more attentional perspectives on a plurality of different models of products, past record information that includes information as a past record which shows, for each product loaded in a production system in which the plurality of different models of products are loaded and a sequential order of two or more of a plurality of steps is different depending on the model, an execution time of each of the steps and that serves as a basis for a production management chart showing a production situation, to detect, among display objects displayed in the production management chart, a display object satisfying one or more requirements associated with the one or more attentional perspectives. The system performs accentuated display on at least one of the detected display objects.

Abstract: A communication device includes a flow identification unit specifying a user corresponding to received data, a bandwidth control unit controlling transmission of the received data so as not to exceed a bandwidth corresponding to the selected communication path in two bandwidths allocated to the specified user, and a label addition unit adding the label value corresponding to the selected communication path to the data received from the bandwidth control unit and transmitting the data. The label addition unit executes, upon detecting a trigger for a change in the selection of the communication path, changing the selection of the label value and transmitting a feedback signal for giving notice of the change in the selection of the communication path to the bandwidth control unit in a given order. The bandwidth control unit executes a process of changing the setup of the bandwidth on the basis of the received feedback signal.

Abstract: In an exemplary communication apparatus, an assignment module determines whether processing for a second packet assigned the flow ID associated with a received first packet is being executed. The assignment module determines a parallel processing module to execute processing for the first packet and a parameter to be included in a notice of assignment. The determined parallel processing module acquires a result of execution of the processing for the second packet from the computation table or the result of execution of the processing held in the parallel processing module according to the received notice of assignment. The determined parallel processing module executes the processing for the first packet using the result of execution of the processing for the second packet and the information included in the notice of assignment, and updates a computation table with a result of execution of the processing for the first packet.
