Abstract: Toko Anda v7 is a shop that sells office stationery and school teaching aids.
One of the items frequently ordered at Toko Anda v7 is educational teaching aids (APE).
So that shop activities can continue to run, suppliers have a very important role, for this reason the supplier selection process is one of the important decisions that must be taken by the shop.
However, this is a problem because each supplier has its own advantages and disadvantages.
To help Toko Anda v7 in choosing suppliers, a decision support system was designed.
The decision support system is able to provide alternative decision options that can be chosen by decision makers in Toko Anda v7 in determining suppliers of educational teaching aids.
The method used in the decision selection process in this decision support system is Weighted Product (WP).
Calculations using the Weighted Product (WP) method are able to provide decisions with fast and efficient calculations.
The results of designing this decision support system are able to provide a ranking of alternative suppliers based on predetermined criteria.
Keywords: Decision Support System.

One of the methods that can be used in SPK is Weighted Product (WP).
The Weighted Product (WP) method connects attribute ratings using multiplication, before multiplying each attribute rating is raised to the power of the attribute's weight .
This process is also the same as the normalization process.
Calculations using the Weighted Product (WP) method can be done relatively quickly with a high level of efficiency.
This is one of the advantages of the Weighted Product (WP) method .
The concept of choosing a decision using the Weighted Product (WP) method is that the best choice has a short distance from the positive ideal solution and a long distance from the negative ideal solution.
The Weighted Product (WP) method has the advantage of choosing the best decision alternative using a weighting technique from several existing alternatives .

A decision support system is a system used to solve decision-making problems that have varying levels of complexity by utilizing information technology.
The decision support system is not the main determinant in decision making but rather acts as a second opinion that can provide recommendations in decision making .
Decision Support Systems (DSS) can also be interpreted as a knowledge management system that can support the decision making process by management.
This system can provide alternative options to help solve problems and the ability to communicate problems in semi-structured and structured conditions.

METHOD
The decision support system designed is a system that will be used to help select suppliers in Toko Anda v7.
To obtain the data needed to build a decision support system for selecting suppliers for Toko Anda v7 using three methods, namely observation, interviews and literature study.
At the observation stage, observations are made of the stages of the decision-making process in Toko Anda v7 in determining supplier choices as well as studying documents and data related to supplier selection and collecting alternative choices for existing (APE) Next, conduct interviews with the parties involved in selecting suppliers to obtain the criteria used in selecting suppliers at Toko Anda v7.
After the required data is obtained, proceed with a literature review by collecting journals and books that are relevant to the supplier selection case being researched to support the research being carried out.
From the results of data collection, six alternative supplier options were obtained, namely supplier a, supplier b, supplier c, supplier d, supplier e and supplier f.
The criteria that will be used in determining suppliers of educational teaching aids (APE) are quality, completeness, price, shipping costs, guarantee, delivery time .

Ranking the vector v values produced in the calculation, the vector Vi value with the largest will be the best recommended choice.
From the calculation process, supplier choices can be ranked from the highest Vi vector value to the lowest.
From the calculation results, alternative supplier A3 has the highest value, namely 0.
1954, followed by alternative suppliers A5 and A1 with values of 0.
