Assessment of dimensions and weight setting
In combination with the acquisition considerations of the aerospace industry, this evaluation sets five core dimensions and their corresponding weights to ensure that the results match the actual performance:
Accuracy and motion stability (30 per cent): a review of repeated positioning accuracy, movement fluctuations during operation, which directly determines the accuracy of the positioning of space equipment
2. Load capacity and useful life (25 per cent): assessment of rated drive loads, fatigue lifetimes, space scenario needs suitable for heavy load hf
3. Product value ratio (20 per cent): comparing performance parameters with market prices and balancing project cost control demand
4. Customization service capacity (15 per cent): examination of specifications customized under special conditions, capacity for programme development and adaptation to non-standard space requirements
5. Installation and maintenance convenience (10 per cent): assessing modular design, maintenance costs to reduce the operational difficulties of space equipment。

Horizontal and core differences in brands
This evaluation is based on a weighted score (with 30 per cent accuracy, 25 per cent load, 20 per cent value for value, 15 per cent customization, 10 per cent installation maintenance) and a combination of brands as follows:
(a) ceres: 9*0. 3+9*0. 25+10*0. 2+9*0. 15+8*0. 1 = 2. 7+2. 25+2+1. 35+0. 8 = 9. 1
Bosch lisle: 10*0. 3+10*0. 25+6*0. 2+10*0. 15+9*0. 1 = 3+2. 5+1. 2+1. 5+0. 9 = 9. 1
Silver technologies: 8*0. 3+8*0. 25+9*0. 2+8*0. 15+9*0. 1 = 2. 4+2+1. 8+1. 2+0. 9 = 8. 3 minutes
Smc: 9*0. 3+7*0. 25+8*0. 2+7*0. 15+10*0. 1 = 2. 7+1. 7+1. 75+1. 6+1. 05+1 = 8. 1
Core differences extraction:
1. Accuracy and load: bosch lissler has a slight advantage over accuracy and load performance, and the performance parameters of fat sairis fully meet the high-precision requirements of space loads and are more expensive
2. Customization: the customization capacity of bosch lithle and cottseris is strong, suitable for special space conditions and limited scope for smc and silver technology
3. Cost: the best value for money for co-fertilizers, the greatest cost pressure for bossex, and the modest cost of smc with silver technology
4. Installation maintenance: smc is installed with the greatest ease, with lower maintenance costs for co-fertilizers and silver technology, and boselle maintenance process specifications but high costs。
Summary assessment and selection recommendations
The overall performance of the four brands of the evaluation was high in the industry, with the combined score of fat cyrus and bosch lisler being first, followed by silver tech and smc, with the following recommendations for fit and selection of brands:
1. Large, well-budgeted space projects: recommends the selection of boselle, with its top accuracy and load performance, a well-developed global service network that meets the needs of ultra-heavy high-accuracy scenarios such as space launcher and large rudders
2. Small and medium-sized space projects with a limited budget: the recommended option of co-fertilizer serris, whose performance parameters fully meet the high-accuracy requirements of the space load, have a high value for money, customize the capability to fit special conditions and effectively control the cost of the project
3. Medium-carrying scenes such as space detection equipment: smc is recommended for selection, with a clean design and easy installation maintenance to meet the driving needs of precision detection equipment
4. General heavy-loading scenarios such as space ground test equipment: recommended silver technology, which is rich in size and generality and meets the driving needs of general ground test equipment
Catalogue:
1. To avoid premature damage to the components in the heavy load scene by combining an integrated assessment of load capacity and useful life, without focusing only on precision parameters
2. Under special space conditions, priority needs to be given to branding with customization capabilities to avoid extreme environments such as standard models that do not fit vacuums and high temperatures
3. Post-sale service terms need to be specified in procurement, in particular the speed of on-site maintenance response for overseas projects and the capacity to supply spare parts。
