AHP model
Objective
In order to analyze the market prospects of the microbial embedding device studied by the hardware group, this paper compares it with the conventional method (the routine method of making algal spheres and other immobilizations in the laboratory is called the conventional method) through the hierarchical analysis method, so as to get the combined utility scores of the two, and then determine that the microbial embedding device has a promising market prospect.
Methodology and Process
Here are the six steps of the AHP model:
1. Introduction to the basic principles and steps in applying the hierarchical analysis approach
The basic principle of Applied Hierarchy Processing (AHP) is a decision-making method that decomposes a complex decision-making problem into multiple levels, and determines the optimal solution by comparing and ranking the criteria and factors at different levels.
2. Detailed description of the study population and data collection methods
The microbial embedding device is an experimental device that allows for the rapid acquisition of algal spheres of the desired diameter by adjusting the infusion rate and the caliber of the injection head, whereas the conventional preparation of algal spheres requires human control.
3. Constructing hierarchies and judgment matrices
In this paper, a hierarchy and judgment matrix is constructed to help consumers make a decision to purchase an algae dropper, as shown in Fig. With the creation of the hierarchy and judgment matrix, consumers can compare and weigh each criterion to choose the most appropriate algae dropper that will achieve their goals and satisfy the factors they value.
4. Fill in the judgment matrix
For each criterion layer and program layer, a corresponding judgment matrix is constructed. The judgment matrix is a positive inverse matrix in which each element represents a comparison of the importance of one criterion relative to another. In the judgment matrix, the rows represent the guidelines being compared, the columns represent the guidelines being compared, and each element in the matrix represents the importance of the guidelines being compared relative to the comparison guidelines. The judgment matrix is filled in based on methods such as expert judgment, questionnaires, or data analysis.
5. Compare and contrast two by two
For a two-by-two comparison between each criterion, a set of scales (e.g., a scale of 1-9) is used to express the relative importance between them. For example, if criterion A has an importance of 5 relative to criterion B, enter the number 5 in row A, column B of the judgment matrix, and the reciprocal of that relative importance in row B, column A.
6. Completion of the judgment matrix
For two-by-two comparisons between each criterion and factor, complete judgment matrices were filled out based on expert opinion or data analysis.
Constructing the hierarchy and judgment matrix is one of the key steps in the AHP method, and they provide the basis for decomposing and comparing the decision problem, which provides the basis for the subsequent weight calculation and program evaluation. Analyze the characteristics and needs of the research object.
By using expert interviews and combining them with qualitative consumer research to derive the full range of consumer decision-making factors when purchasing a device for making algal spheres, it was possible to select key decision-making factors from the full range of consumer purchasing decision-making factors, based on the particular characteristics of the dropper ball injector.
Apply hierarchical analysis for decision-making or assessment.
After asking the experts and combining the results of the questionnaire survey, a judgement matrix was obtained, and then a consistency test was carried out on the judgement matrix to ensure that there would be no contradictions, and the formula was as follows:
n is the number of indicators (i.e., the number of rows of the judgement matrix).1,2 is the average stochastic consistency indicator, and the RI corresponding to different matrix orders is obtained by looking up the table.
Calculated CR=0.0348,CR<0.1 passed the consistency test.
Summary
From the combined score of the two, it can be seen that the microbial embedding device is superior to the conventional method of preparing algal spheres, and the microbial embedding device does not appear on the market today, so the microbial embedding device has a broad market, and it also greatly helps the hardware group to understand the prospects of the embedding device and the shortcomings of the conventional device, and it can better help the hardware group to research and develop the hardware.
Microbial encapsulation is a technological solution for efficient and sustainable wastewater treatment. It has major advantages over traditional physico-chemical treatment methods. Microbial embedding offers the possibility of a sustainable and efficient wastewater treatment solution. It can replace traditional physicochemical treatment methods, reduce treatment costs and dependence on external energy sources, facilitate research on microbial immobilization and wastewater treatment, and provide a sustainable solution for future bioenergy and green chemistry.
In this paper, a model was established through hierarchical analysis, and a comparison was carried out between the microbial embedding device and the conventional method (the conventional method of making algal spheres and other immobilization in the laboratory is called the conventional method), and it was found that the microbial embedding device has a broad market prospect.
