Printing Production Schedule Informationization Analysis and Case Discussion 1

Summary

With the rapid development of information technology, "computing" is already a basic function for computers. However, at present all levels of computers, there are a large number of related time-controlled application software. In print production management, the focus is on print production scheduling and schedule control. A good print production scheduling control system can display the load of a process or equipment and compare it with its standard production capacity. This paper not only discusses the importance of printing scheduling management system, but also cooperates with Microsoft to launch a new version of Microsoft Project98. This software is used to simulate printing production scheduling operations and achieve the ultimate goal of schedule control.

Preface

In the era of rapid changes and fierce competition, the relationship between technology and management is getting closer. On the one hand, technology can enhance its application level through management and maximize its effectiveness. On the other hand, management must also be assisted by technology to improve the competitiveness of enterprises. With the rapid development of computer technology, in the field of printing, computer digital information has gradually replaced the pre-press printing department in the past. It has also been introduced into printing and post-press processing. The printing production schedule can be said to be quite complicated work. The process needs to understand the details of the related operations of each print and have different plans according to the differences in the prints, and within the time limit specified by the customer. , do effective production planning. This article will use Microsoft Project98 software to plan printing production schedules, and use appropriate form statements to regulate the planning of the prints and the print schedules and other operations, and effectively manage the print production and operations.

è´°, printing production scheduling and schedule control

First, the purpose of print production scheduling control

(a) to understand the progress of the print and predict the date of completion

A medium-sized and large-scale printing company may, at any one time, have dozens or even hundreds of simultaneous prints at the same time. The production schedule of each print will change at any time when faced with customers. Even when the internal management staff or the business asks progress, how to answer the above information in the shortest time is the goal that the printing production scheduling control system should achieve.

(B) equipment load arrangements to understand the bottlenecks

A good printing production scheduling control system should be able to indicate the load condition of a process or equipment and compare it with its standard production capacity. When it exceeds its standard production capacity, it can be handled in an overtime manner or outsourcing process. In order to avoid delays in the delivery of prints, the company's credibility will be affected.

(c) Reduce the impact of dispatches

There is absolutely no print production scheduling system or unsuitable printing production scheduling control system. Often, the printed matter that has been produced for enough time becomes urgent, causing chaos in production operations and even requiring overtime or outsourcing. Processing methods.

(d) Reducing overtime and non-productive hours

As mentioned above, a good printing production scheduling control system can reduce overtime and non-production hours and reduce production costs. Conversely, a poor printing production scheduling control system often erodes. Although this intangible waste is more difficult to estimate, it is obviously felt by all production control and online staff.

(E) Create more performance to enhance the company's image

Since most of the prints can be delivered on time, winning the trust of customers and establishing a good relationship with each other, the image of the company is virtually enhanced, and customers are also willing to hand over more copies to the printing company to create more business results.

Second, printing production process and form report management

To be able to effectively do a good job of printing production and job management, a clear process and the use of appropriate form report management is absolutely necessary. If the process is not clear or even confusing, such as the salesman directly to the production of the print to the scene, and can not be the first to the control center to do the print planning and printing schedules and other operations, is bound to cause printing The confusion of production management operations. Each department needs to send the progress of the progress of the department to the control center every day in order to compare with the expected progress. Since the actual progress will be different due to various unpredictable conditions and scheduled progress, the report of the completion status is extremely important to the control center personnel. The control personnel made some information to understand the problems encountered during the entire production process, and made several corrections to the production plan to avoid progress or backwardness, and the delay occurred in the printing or the machine caused downtime because the subsequent prints could not be connected. The phenomenon. Here are some common progress control forms:

Schedule schedule

2. Load table

3. Sample signature

4. Subcontract processing receipts

5. Production date report

6. Delivery date report

Third, the general problem of printing scheduling control

(I) Accepting non-corporate equipment suitable or good at the print

As each printing company has its own production equipment system, these equipment systems have been able to fully understand the market demand, their expertise, and the chosen purchase structure after analyzing the internal and external environment of the company. If it is a company salesman or management, in order to increase the performance or provide the customer with a full range of services, the customer may be promised to accept the prints that are not suitable for the equipment of the company, or they are not good at the prints. experience. For example, a printing company that prints catalogues, posters, and magazines will take the form used by the client company. Of course, it is understandable to stand in a position to provide a full-service position, but if it does not know how to print it, it will still be self-published. Printing, it will increase unnecessary production hours, and cause schedule management personnel trouble, and production confusion.

(B) Unreasonable printed copies due

The standard production time required for the printed product received by the customer is shorter than the production time given by the customer. The result is not the customer's complaint caused by delayed delivery; To other customers' rights, this is a phenomenon that a healthy schedule control system should not have.

(3) No maintenance time is reserved

In order to operate effectively and maintain a certain level of quality, printing equipment must be regularly maintained. If it is not possible to prioritize the scheduled maintenance time when planning a schedule, it is either a neglect of the maintenance or an imprint. The delay phenomenon.

(4) The standard production capacity of equipment and various departments has not been established

The establishment of standard production capacity for equipment and various departments can be said to be a prerequisite for the establishment and improvement of the printing production scheduling control system. If the standard production capacity is not established, the schedule control personnel will not have any standards to follow, and it is easy to cause equipment overload or Underload phenomenon.

叁, printing production management information system analysis

Printing production management system under the computer-based construction can be of great help for printing production management related operations, such as printing valuation, print cost analysis, manufacturing cost analysis, inventory status report, machine type load sheet, department Do not print the load table and equipment personnel status report. However, in conjunction with computer networks, manufacturing departments and inventories can directly input completion status or any other transaction-related matters through the terminal. The control center can grasp the latest production information. This article will only analyze and discuss the print production schedule.

First, the function of the printing scheduling control system should have

A good printing scheduling control system, whether manual or computerized printing scheduling control system, should at least have the following basic functions:

1. At any one time, you can answer the current actual progress of each print. 2. It can clearly show the current negative situation and capacity of each cost center (equipment or process).

3. Ability to compare the standard capacity of each cost center (equipment or process) with the current workload of scheduled print jobs.

4. The operator can clearly know the sequence of his work according to this scheduling system.

5. It can be pointed out which cost centers (devices or processes) must not be behind in the progress of the print, otherwise it will not be delivered on time.

6. Can show that some prints have been delayed and provide management personnel with emergency response.

Second, the tools used by the printing schedule control system

The Critical Path Method (CPM) is a project management method that is often used in the industry. However, because the printing industry has more production variables, it generally does not use the trail method. On the other hand, the most used tools in the printing industry for scheduling and schedule control are still the so-called Gant Charts. Gantt is named after Henry L Gantt, one of the fathers of scientific management. Gantt charts can have many different forms, the most common being time (date, hour) listed on the horizontal axis, and the vertical axis for the machine equipment or cost center (cost center). Process, drawing the start and completion time of each machine or process (cost center), this is the so-called schedule board. If using a computer scheduling system, this schedule can also be displayed on a computer screen. Another form of Gantt chart is to change the cost center (equipment or process) originally listed on the vertical axis to the name of the print, and the horizontal axis to the production departments and to list each print in each department. The start and finish time. The advantage of this form of Gantt Chart is that the progress of each print is clear at a glance, but the disadvantage is that it is impossible to know the load of each cost center. It is unknown whether there is any remaining capacity or already overloaded. There is also a form of schedule control table in which the cost center or the machine identification table is placed at the top, and the related prints in this cost center or machine production are placed in this cost center or machine identification table. Below, the main purpose is to show the cost of the load on the machine or the machine. This type of control system, strictly speaking, can only be said to be a job tracking system (job tracking system). This cannot be called a scheduling system. Since the production schedule changes at any time, if the schedule cannot be updated at any time, this schedule will not have any schedule control function. In the case of a schedule, the schedule schedule should be updated at least twice. When the schedule control table is completed, the daily distribution of the various departments can be completed the previous day.

Third, the establishment of standard production capacity of equipment and various departments

Empirical method

The empirical estimation method generally refers to the work experience of the foreman or field supervisor and determines the standard operating time for a certain process. Before the initial production of any production standard production capacity, the empirical estimation method can be said to be the only method that can be used, but this method is easy to subjective, and its accuracy is not high.

2. Historical records

The historical record method can be said to be the method most commonly used by general printing factories to establish production standards. Its correctness depends on the method of its dataset and the rigor of the personnel providing the information. If the data methods and procedures are extremely loose, then the information they receive will also be unreliable
