BRIEF DESCRIPTION OF THE INVENTION

[0039] A Product optimization tool according to a preferred embodiment of the present invention is herein described in the following description

DETAILED DESCRIPTION OF THE INVENTION

[0040] A Product optimization tool thereof is herein described with numerous specific details to provide a complete understanding of the invention. However, these specific details are exemplary details and should not be treated as a limitation to the scope of the invention.

[0041] Throughout this specification, the word “comprises” or variations such as “comprises or comprising”, will be understood to imply the inclusions of a stated element, integer or step, or group of elements, integers, or steps, but not the exclusions of any other element, integer or step or group of elements, integers, or steps.

[0042] A method is described herein for optimal production in a paint shop facility. The disclosed tool is a product planning tool that has been specifically designed to help the paint shop plan its production operations. It allows users to plan the furniture items that will be painted, the sequence in which they will be painted, the production line that will be used, the optimum quantity of each furniture item to be painted and the record of various Stock Keeping Units (SKU’s).

[0043] This can be accomplished through a system, which includes a user-friendly interface, and it also allows easy input and management of production data.

[0044] The production amount and production sequence of various products have to be rationalized based on user requirements, changeovers needed during production, constraints of the product, sequence of paint colour, variation of furniture size, determination of next production line to be used for painting, planning production and real-time stock availability. The optimal production tool found using this method described herein can help establish useful resource allocation and help to effectively sequence the production.

[0045] The processing module acquires data from the user, wherein the user uploads production information like Buffer penetration report, Backlog line 1 report and Backlog line 2 report via the input screen which contains the maximum capacity constraint details, wherein the Buffer Penetration Report contains details of the number of units in stock, number of units in transit stock, number of units in stock at the plant, representation of market demand based on pending orders and Branch targets are represented in the Buffer Penetration Report. It gives real-time information about the existing and in-demand stock units, which is signified by four major colour codes; White / Green / Black / Yellow, wherein the colour white indicates that the entire product is available in stock, and Black colour indicates that the product is low on inventory, Green and Yellow colour indicates the existing stock in inventory in percentage form.

[0046] Backlog file 1 and Backlog file 2, indicate the item that is not considered in the maximum constraint. These items are the ones which were not produced on the predicted date and hence are added to the backlog file.

[0047] The above-obtained data is further processed by the system which results in a set of output data, that is represented by an Output Report. This report Output is the end part of the production line. Once previously selected various types and quantities of products and thecolour coating, the user can download the optimized files in this section. It consists of Paint shop line 1, Paint shop line 2, Daily plan and Unsequenced Plan. This report is available for downloading purposes, wherein the paint shop line 1 and Paint shop line 2 contain the production line timetable and backlog details, the unsequenced schedule represents the item Codes and their quantities which are selected by the optimizer based on various family and quantity constraints. This plan does not consider the Paint Shop time constraints in a day. It is the first thing generated by the system, which includes a description of products, family powdercoating colour, quantity, minimum order quantity, priority and colour status of the product.

[0048] The daily plan represents the sequence of colour, quantity and time that a production line has to optimize for the production of a product. Represents the items that need to be manufactured and painted. It shows the item codes, and their respective quantities present in both timetables. The daily plan is used to convey to the metal shop about the items that need to be kept ready on (n+4) day for the paint shop.

[0049] As depicted in FIG. 6, which is a block diagram that describes a System 100, according to some embodiments of the present disclosure. In some embodiments, the System 100 may include inventory data 110 receiving means, previous backlog production data 120 receiving means, an order data means 130 for receiving detail about the products to be painted, constraints configuration means 140 for configuration of the constraints of the production system, product allocation 170, and scheduling means 180 for allocation of the products for painting to the production line and scheduling the painting on the the selected production line based on the production goal.

[0050] In some embodiments, the System 100 may also include production plan generation means 150 for generating a production plan based on the the inventory data 110 (a), the previous backlog production data 120 (b), the order data details (c), and the constraints of the production system (d).
