Comparative analysis of manufacturing processes of various designs of sliding doors in the hall

Abstract

A comparison of the economic efficiency of investment investments of technological processes for the manufacture of hallway doors from different materials and different structures from a set of furniture for the corridor was made. The necessary materials for two types of production of facade surfaces were selected and calculated - sliding doors for the hallway, which are included in the wardrobe wall set, made of different materials from natural wood. The necessary basic equipment was selected and calculated in accordance with the developed production technologies for two options for the production of facade surfaces - sliding doors for hallways. The necessary technological routes were selected, developed and calculated for each variant of the production of facade surfaces - sliding doors for hallways. The necessary equipment has been calculated in order to technologically perform two variants of sliding doors - entrance hall facades using different materials - natural wood and MDF boards/board. Two shop plans are proposed according to the developed technologies for the production of facade surfaces. A rational technological process for the production of facade surfaces - sliding doors for hallways is proposed. The effectiveness of choosing one technological process for a certain facade of the hallway, which is included in the set of wardrobe walls made of different materials, is calculated and determined. It has been calculated and substantiated that it is worth choosing option number two for the production of facades from block elements, since there is a much smaller investment investment of UAH 50,816.05 thousand (for the first one - UAH 149,712.39 thousand), that is, the value of the comparative economic efficiency indicator is lower. albeit with a longer payback period of 0.85 compared to 0.27.
