The programming of work has to be done, for products or projects to meet the criteria of logical sequencing and criteria related to good sense of the one who plans, for that reason it is essential that the task of planning is done with the help of a decision support system in production planning and not an automated tool for planning.
For these reasons, the tool developed by SISTRADE has a large participation and interactivity with the people responsible for planning. This solution enables scheduling the company's activities on time and allocating to each of the available resources/machines according to a set of priority criteria, as well as assigning the employees who will participate in the production of a given operation. It is a tool based on Gantt chart, where one of the axes represents the resources and the other represents the time horizon. This is a dynamic and interactive system, allowing the manager to anticipate production alterations and this way to send alerts to the real-time production.
- Assisted production simulation;
- Operation or activities planning in Gantt chart;
- Operations sequencing in a tabular format;
- Assisted scheduling of employees;
- Matrix-based scheduling of operations/employees;
- Real-time indexing of the beginning and end of production;
- Load analysis and resource/machine availability;
- View in Gantt charts;
- Operation status identification through colours;
- Multi-user planning.
SCHEDULING – PLANNING OF ACTIVITIES
The scheduling is the module responsible for the scheduling of job orders in Gantt chart through the algorithm of capability planning. Using Gantt chart enables the real scheduling or simulation of production planning.
This module allows the user a graphic view of the production status online. In addition, it is also possible to update the information of job orders in an easy and intuitive way. To do this, it is necessary to select each job order and drag it to the new desired location and record the results. This feature is called Drag and Drop, allowing the user to simulate the planning horizontally and vertically on Gantt.
In job orders with various components (cover, book-block, insert) it is possible to define the operation where the different components are joined as subsequent planned operations after the operations of each component are finalized. This configuration was called “Dependency between the components”, it is configurable in each Job Order. When the Job Order is planned, the scheduling algorithm incorporates this restriction, ensuring the correct sequence of an operation routing to be performed.
For the companies where the internal scheduling task is carried out by a team of individuals, the scheduling is provided with multi-user functionality, thereby allowing the production planning to be made by more than one user, so the system controls the time at which each user is making the recalculation of scheduling, preventing the other users from making the scheduling changes. The control of multi-user is extended to include the features “Job Orders for Scheduling” and “Remove Job Orders from Scheduling”. The control, whenever it detects the changes made by a user, shows the other users the information messages in order to refresh the screen to see the last version.
It is worth mentioning other planning features such as:
- Set operations at a particular time, time/date, in order to answer questions such as the customer is going to approve the work at a specific time;
- The idle time of material before starting the next process, to ensure for example, drying times;
- Forecast of the reception of material for the JO for the printing resources, making the system analyse the forecasts of material receipts (minimum date) for the Job Order;
- Recalculation of the scheduling from the particular date and so that it does not affect days/job orders that have already been set by the user.
In situations where Gantt is overloaded with several jobs and it is complicated to make Drag and Drop of various operations, the user is provided with the tabular scheduling assistant, making it possible to reorder the sequence of operations for each resource/machine through the selection list. This feature can be used detailed by signature or a higher than the component level, as the user will make the adjustments to the components sequence, ensuring the system the sequence of signatures that is clear for the user.
Sistrade®, without stopping or changing the planning, can estimate the beginning and end date to produce a job order out of planning. The dates obtained are purely informative since this feature is not reflected in production. Sistrade® also allows sending a load chart, showing for each machine and delivery times, capacity, volume of orders and availability.
Each bar is an operation of a particular job order, the background colour is the status of that job order. For example, it is red because it does not meet the deadline, it is green because it is produced, grey means being within the agreed deadline, the blue spot indicates the time taking longer to produce. To summarize, visually and graphically, production managers have a clear understanding of the position of each job and this way make decisions in accordance with feedback of this tool.
SCHEDULING – PLANNING OF EMPLOYEES
The planning of employees is the second perspective allowing the user to inter-cross the scheduled job order operations with the employees.
This feature allows the user to define visually the different teams of employees who will be involved in the execution of a particular job order operation in an easy and intuitive way. To do this, simply double-click on the intersection between Employee and Job Order/Operation, to assign the employee to the operation automatically. After matrix-based scheduling of the employees with the operation, it is possible to define the quantity to produce and the specific comments for the employees/operation.
It is also possible to define comments by day and by employee in order to indicate some information, for example, some last minute details provided by the customer.
SCHEDULING – DYNAMIC PLANNING
This is a dynamic not static programming tool, as it is successively being upgraded with the beginning and end of production recorded in shop floor control. These inputs may even come from a wireless terminal or a PDA with an internet connection.
This dynamic interconnection with the collection is supported in the definitions of the alternative resources by operation, thus ensuring that the situations in which control of production does not follow the sequence and planning-defined machines, the planning is responsible for the dynamic correspondence between planning and production.
