Application of supplier evaluation statistics module developed by PHP in enterprise resource planning (ERP) system

Introduction:
With the increasing globalization and market competition, enterprises are paying more and more attention to supply Chain management and optimization. The application of supplier evaluation statistics module in enterprise resource planning (ERP) systems has attracted more and more attention from enterprises. This article will introduce how to use PHP to develop a simple supplier evaluation statistics module, and demonstrate the application of this module in the ERP system.

1. Module Function Introduction
   The supplier evaluation statistics module is used to evaluate and rank the company's suppliers, and formulate corresponding improvement measures based on the evaluation results. The module mainly includes the following functions:
2. Supplier information management: record the basic information of suppliers, including name, contact person, contact information, etc.
3. Evaluation indicator setting: Define the indicators and weights for supplier evaluation, such as delivery on-time rate, quality control, service level, etc.
4. Evaluation record maintenance: record the results of each evaluation, including ratings and evaluation opinions.
5. Statistical analysis report: Generate supplier evaluation reports based on evaluation records, and summarize and analyze them.
6. Module development and implementation
   In order to allow readers to better understand the development process of the supplier evaluation statistics module, a simple example will be demonstrated below. Suppose we need to evaluate and count the supplier's delivery on-time rate.

First, we need to create a database table to save supplier information and evaluation records:

CREATE TABLE `supplier` (
  `id` INT(11) NOT NULL AUTO_INCREMENT,
  `name` VARCHAR(50) NOT NULL,
  `contact` VARCHAR(50) NOT NULL,
  `phone` VARCHAR(20) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

Then, we need to create another database table to save supplier evaluation records:

CREATE TABLE `evaluation` (
  `id` INT(11) NOT NULL AUTO_INCREMENT,
  `supplier_id` INT(11) NOT NULL,
  `delivery_rate` DECIMAL(5,2) NOT NULL,
  `comments` TEXT NOT NULL,
  PRIMARY KEY (`id`),
  FOREIGN KEY (`supplier_id`) REFERENCES `supplier` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

Next, we use PHP to create the basic functions of the supplier evaluation statistics module:

// 连接数据库
$host = 'localhost';
$db = 'erp';
$user = 'root';
$password = 'password';
$dsn = "mysql:host=$host;dbname=$db;charset=utf8";
$pdo = new PDO($dsn, $user, $password);

// 添加供应商信息
function addSupplier($name, $contact, $phone) {
    global $pdo;
    $stmt = $pdo->prepare("INSERT INTO supplier (name, contact, phone) VALUES (?, ?, ?)");
    $stmt->execute([$name, $contact, $phone]);
    return $pdo->lastInsertId();
}

// 添加评价记录
function addEvaluation($supplierId, $deliveryRate, $comments) {
    global $pdo;
    $stmt = $pdo->prepare("INSERT INTO evaluation (supplier_id, delivery_rate, comments) VALUES (?, ?, ?)");
    $stmt->execute([$supplierId, $deliveryRate, $comments]);
    return $pdo->lastInsertId();
}

// 生成评价报表
function generateReport() {
    global $pdo;
    $stmt = $pdo->prepare("SELECT supplier.name, AVG(evaluation.delivery_rate) as average_rate 
                          FROM supplier INNER JOIN evaluation ON supplier.id = evaluation.supplier_id 
                          GROUP BY supplier.id");
    $stmt->execute();
    return $stmt->fetchAll(PDO::FETCH_ASSOC);
}

3. Application in the ERP system
   The supplier evaluation developed above The statistical module is integrated with the enterprise's ERP system and can provide the following applications for the enterprise:
4. Supplier selection and screening: Based on the supplier's evaluation report, the enterprise can select and screen suppliers more accurately to provide better quality products and services.
5. Supply chain optimization: By regularly evaluating and counting supplier performance, companies can discover bottlenecks and problems in the supply chain and optimize and improve them.
6. Establish a good cooperative relationship: Based on the supplier's evaluation results, the company can jointly develop improvement measures with the supplier and establish a long-term and stable cooperative relationship.

Summary:
This article introduces the application of the supplier evaluation statistics module developed by PHP in the enterprise resource planning (ERP) system. By developing a simple supplier evaluation statistics module and demonstrating how to integrate it with an enterprise's ERP system, it can help enterprises better manage and optimize the supply chain and provide better products and services. In practical applications, the functions of the supplier evaluation statistics module can also be expanded and customized according to the needs of the enterprise to meet the needs of different enterprises.
