VB.NET语言下的供应链系统供应商绩效评估体系实现

在供应链管理中,供应商绩效评估是一个至关重要的环节。它有助于企业了解供应商的表现,优化供应链关系,提高整体供应链效率。本文将围绕VB.NET语言,探讨如何实现一个简单的供应商绩效评估体系。

系统需求分析

在开始编写代码之前,我们需要明确系统的需求。以下是一个基本的供应商绩效评估体系需求分析:

1. 数据录入:允许用户录入供应商的基本信息,如供应商名称、联系方式等。
2. 绩效指标设置:定义评估供应商的绩效指标,如交货准时率、产品质量、价格竞争力等。
3. 评分标准:为每个绩效指标设定评分标准,如满分、扣分等。
4. 绩效评估:根据供应商的表现,对绩效指标进行评分。
5. 结果展示:以图表或表格形式展示供应商的绩效评估结果。
6. 数据统计与分析:对评估结果进行统计分析,为决策提供依据。

系统设计

数据库设计

为了存储供应商信息和评估数据,我们需要设计一个数据库。以下是一个简单的数据库设计:

- 供应商表(Suppliers):
- SupplierID:供应商ID(主键)
- SupplierName:供应商名称
- ContactName:联系人姓名
- ContactPhone:联系电话
- ContactEmail:联系邮箱

- 绩效指标表(PerformanceIndicators):
- IndicatorID:绩效指标ID(主键)
- IndicatorName:指标名称
- MaxScore:满分
- DeductionRate:扣分率

- 评估记录表(EvaluationRecords):
- RecordID:评估记录ID(主键)
- SupplierID:供应商ID(外键)
- IndicatorID:绩效指标ID(外键)
- Score:得分

系统架构

系统采用B/S架构,分为前端和后端两部分:

- 前端:使用VB.NET WinForms或WPF进行界面设计。
- 后端:使用VB.NET进行业务逻辑处理,连接数据库。

代码实现

以下是一个基于VB.NET的简单供应商绩效评估系统实现:

数据库连接

vb.net
Imports System.Data.SqlClient

Public Class DatabaseConnection
Public Shared Function GetConnection() As SqlConnection
Dim connectionString As String = "Data Source=YOUR_SERVER;Initial Catalog=YOUR_DATABASE;Integrated Security=True"
Return New SqlConnection(connectionString)
End Function
End Class

供应商信息录入

vb.net
Public Class SupplierForm
Private Sub SaveButton_Click(sender As Object, e As EventArgs) Handles SaveButton.Click
Using connection As SqlConnection = DatabaseConnection.GetConnection()
connection.Open()
Dim command As SqlCommand = New SqlCommand("INSERT INTO Suppliers (SupplierName, ContactName, ContactPhone, ContactEmail) VALUES (@SupplierName, @ContactName, @ContactPhone, @ContactEmail)", connection)
command.Parameters.AddWithValue("@SupplierName", SupplierNameTextBox.Text)
command.Parameters.AddWithValue("@ContactName", ContactNameTextBox.Text)
command.Parameters.AddWithValue("@ContactPhone", ContactPhoneTextBox.Text)
command.Parameters.AddWithValue("@ContactEmail", ContactEmailTextBox.Text)
command.ExecuteNonQuery()
End Using
End Sub
End Class

绩效指标设置

vb.net
Public Class IndicatorForm
Private Sub SaveButton_Click(sender As Object, e As EventArgs) Handles SaveButton.Click
Using connection As SqlConnection = DatabaseConnection.GetConnection()
connection.Open()
Dim command As SqlCommand = New SqlCommand("INSERT INTO PerformanceIndicators (IndicatorName, MaxScore, DeductionRate) VALUES (@IndicatorName, @MaxScore, @DeductionRate)", connection)
command.Parameters.AddWithValue("@IndicatorName", IndicatorNameTextBox.Text)
command.Parameters.AddWithValue("@MaxScore", MaxScoreNumericUpDown.Value)
command.Parameters.AddWithValue("@DeductionRate", DeductionRateNumericUpDown.Value)
command.ExecuteNonQuery()
End Using
End Sub
End Class

绩效评估

vb.net
Public Class EvaluationForm
Private Sub SaveButton_Click(sender As Object, e As EventArgs) Handles SaveButton.Click
Using connection As SqlConnection = DatabaseConnection.GetConnection()
connection.Open()
Dim command As SqlCommand = New SqlCommand("INSERT INTO EvaluationRecords (SupplierID, IndicatorID, Score) VALUES (@SupplierID, @IndicatorID, @Score)", connection)
command.Parameters.AddWithValue("@SupplierID", SupplierComboBox.SelectedValue)
command.Parameters.AddWithValue("@IndicatorID", IndicatorComboBox.SelectedValue)
command.Parameters.AddWithValue("@Score", ScoreNumericUpDown.Value)
command.ExecuteNonQuery()
End Using
End Sub
End Class

结果展示

vb.net
Public Class ResultForm
Private Sub LoadButton_Click(sender As Object, e As EventArgs) Handles LoadButton.Click
Using connection As SqlConnection = DatabaseConnection.GetConnection()
connection.Open()
Dim command As SqlCommand = New SqlCommand("SELECT FROM EvaluationRecords", connection)
Dim reader As SqlDataReader = command.ExecuteReader()
DataGridView1.Rows.Clear()
While reader.Read()
DataGridView1.Rows.Add(reader("SupplierID"), reader("IndicatorID"), reader("Score"))
End While
reader.Close()
End Using
End Sub
End Class

总结

本文介绍了如何使用VB.NET语言实现一个简单的供应链系统供应商绩效评估体系。通过以上代码,我们可以实现数据录入、绩效指标设置、绩效评估、结果展示等功能。实际应用中,系统可能需要更加复杂的功能和更完善的数据库设计。希望本文能对您有所帮助。
