Using PHP to develop an enterprise resource planning (ERP) system that implements production scheduling functions

Use PHP to develop an enterprise resource planning (ERP) system that implements production scheduling functions

The enterprise resource planning (ERP) system is an integrated management software that can help enterprises comprehensively manage the resources and processes of various departments , to improve the efficiency and effectiveness of organizational operations. In the field of production, production scheduling is a very important link, which involves the reasonable planning and utilization of production resources to ensure the smooth progress of the production process. This article will introduce how to use PHP to develop an ERP system that implements production scheduling functions, and give code examples.

First of all, we need to clarify the basic requirements and processes of the production scheduling function. In an ERP system, the production scheduling function usually includes the following aspects:

1. Production plan management: Develop production plans and schedule production based on orders and inventory conditions.
2. Resource management: Manage the manpower, equipment, raw materials and other resources required for production to ensure the execution of the production plan.
3. Scheduling management: Scheduling and arranging production tasks according to the production plan and resource conditions, including allocating workers, equipment and raw materials, etc.
4. Progress Tracking: Monitor the execution of production tasks in real time, including the start and end time and progress of the task.

Next, we can use PHP language and MySQL database to implement these functions. First, we need to create a database and design the relevant table structure. The following is a simplified database design:

# 订单表
CREATE TABLE orders (
    id INT PRIMARY KEY AUTO_INCREMENT,
    order_number VARCHAR(50),
    product_id INT,
    quantity INT,
    deadline DATE
);

# 产品表
CREATE TABLE products (
    id INT PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(50)
);

# 资源表
CREATE TABLE resources (
    id INT PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(50),
    capacity INT
);

# 任务表
CREATE TABLE tasks (
    id INT PRIMARY KEY AUTO_INCREMENT,
    order_id INT,
    resource_id INT,
    start_time DATETIME,
    end_time DATETIME,
    status INT
);

For the production planning management function, we can provide a simple form to enter order information and save it to the database:

<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $order_number = $_POST['order_number'];
    $product_id = $_POST['product_id'];
    $quantity = $_POST['quantity'];
    $deadline = $_POST['deadline'];

    // 将订单信息插入到数据库中
    $query = "INSERT INTO orders (order_number, product_id, quantity, deadline) 
              VALUES ('$order_number', $product_id, $quantity, '$deadline')";
    
    // 执行插入操作

}
?>

<form method="POST" action="">
    <label for="order_number">订单号：</label>
    <input type="text" name="order_number" id="order_number" required><br>

    <label for="product_id">产品：</label>
    <select name="product_id" id="product_id" required>
        <option value="1">产品1</option>
        <option value="2">产品2</option>
        <!-- 其他产品选项 -->
    </select><br>

    <label for="quantity">数量：</label>
    <input type="number" name="quantity" id="quantity" required><br>

    <label for="deadline">截止日期：</label>
    <input type="date" name="deadline" id="deadline" required><br>

    <input type="submit" value="提交">
</form>

For resource management and For the scheduling management function, we can provide a task list to view and operate task information, and update the task status to the database in real time:

<?php
// 获取任务列表
$query = "SELECT t.id, o.order_number, p.name AS product_name, r.name AS resource_name, t.start_time, t.end_time, t.status 
          FROM tasks t
          INNER JOIN orders o ON t.order_id = o.id
          INNER JOIN products p ON o.product_id = p.id
          INNER JOIN resources r ON t.resource_id = r.id";

// 执行查询操作

// 显示任务列表
while ($row = /* 获取查询结果 */) {
    echo '<tr>';
    echo '<td>' . $row['order_number'] . '</td>';
    echo '<td>' . $row['product_name'] . '</td>';
    echo '<td>' . $row['resource_name'] . '</td>';
    echo '<td>' . $row['start_time'] . '</td>';
    echo '<td>' . $row['end_time'] . '</td>';
    echo '<td>' . ($row['status'] === '1' ? '进行中' : '已完成') . '</td>';
    echo '</tr>';
}

// 更新任务状态
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $task_id = $_POST['task_id'];
    $status = $_POST['status'];

    // 更新任务状态到数据库中
    $query = "UPDATE tasks SET status = $status WHERE id = $task_id";
    
    // 执行更新操作

}
?>

<table>
    <tr>
        <th>订单号</th>
        <th>产品</th>
        <th>资源</th>
        <th>开始时间</th>
        <th>结束时间</th>
        <th>状态</th>
        <th>操作</th>
    </tr>
    <!-- 显示任务列表 -->
</table>

<form method="POST" action="">
    <label for="task_id">任务ID：</label>
    <input type="text" name="task_id" id="task_id" required><br>

    <label for="status">状态：</label>
    <select name="status" id="status" required>
        <option value="1">进行中</option>
        <option value="2">已完成</option>
    </select><br>

    <input type="submit" value="更新">
</form>

Finally, for the progress tracking function, we can use Ajax technology to achieve real-time updates Effect. The following is a simple Ajax code example:

$(document).ready(function() {
    setInterval(function() {
        $.ajax({
            url: 'task_status.php',  // 后端处理代码
            success: function(data) {
                // 更新任务状态
            }
        });
    }, 1000);
});

Through the above code example, we can implement the production scheduling function in the ERP system and implement core functions such as production plan management, resource management, scheduling management, and progress tracking. . Of course, the above code is just a simplified example, and actual ERP systems need to consider more details and security issues.

To sum up, by using PHP language and MySQL database, we can develop an enterprise resource planning (ERP) system with complete production scheduling functions to improve production efficiency and benefits. I hope that the introduction and code examples of this article can provide some help for readers to understand and practice the development of ERP systems.
