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.

System and method for supporting production management

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.

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. Execution 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).

A support system displays, on the basis of management information as a past record which shows, for each product loaded in a production system in which a 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, at least one of a first holistic chart (having a time axis and showing a feature value of production situation of the product during a display target period on a per predetermined unit basis) and a second holistic chart (showing a relationship between a plurality of steps with respect to a flow of a plurality of models of products). The support system selects at least one of a model and a step for one of the holistic charts, and displays step element information.

In a data retrieval/distribution apparatus which retrieves designated information from the collected data in accordance with a retrieval/distribution request sent from a data retrieval/distribution client, and sends a retrieval result to the data retrieval/distribution client, the data retrieval/distribution client sends, to the data retrieval/distribution server, the retrieval/distribution request including a first retrieval condition using a virtual data conversion definition, which is a virtualization of data conversion definitions as a definition for converting the collected data into a distribution format, a processing unit of the data retrieval/distribution apparatus generates a second retrieval condition using each of the data conversion definitions from the first retrieval condition, executes retrieval processing according to the generated second retrieval condition, and sends a retrieval result of the retrieval processing to the data retrieval/distribution client as a retrieval result according to the first retrieval condition.

Data retrieval/distribution method and apparatus, and storage medium

Proposed are a management apparatus and a management method capable of improving the stability of the overall computer system. In a computer system which manages a storage area provided by each of a plurality of mutually connected storage apparatuses as a logical pool, provides to a host computer a virtual volume associated with the logical pool, and assigns a real storage area from the logical pool to the virtual volume when the host computer writes into the virtual volume, when a storage apparatus is added to the plurality of storage apparatuses, the host computer is controlled to switch the access path to the added storage apparatus.
