1. Static Inventory Problem Under Risk

Definition

A static inventory problem under risk involves a single-period decision where demand is uncertain but follows a known probability distribution. Examples include seasonal products like newspapers, ice cream, or festival items.

General Characteristics

• Single Period Decision: A one-time decision with no repeated ordering.
• Uncertain Demand: Demand is not fixed, though probabilities are known.
• Risk Factors: Potential for overstock or understock.
• No Replenishment: Stock cannot be reordered within the same period.
• Probabilistic Approach: Decisions are based on expected values.
• Cost Consideration: Includes overstock (unsold goods) and understock (lost sales) costs.
• Objective: Maximize expected profit or minimize

Marketing Fundamentals

American Marketing Association (AMA): Marketing is the activity, set of institutions, and processes for creating, communicating, delivering, and exchanging offerings that have value for customers, clients, partners, and society at large.

Philip Kotler's Definition: Marketing is the process of managing profitable customer relationships.

Strategic vs. Tactical Marketing

• Strategic Marketing: Focuses on value proposition, market segmentation, targeting, positioning, and brand equity.
• Tactical Marketing: Involves the marketing plan, the 4Ps (Product, Price, Place, Promotion), digital marketing, search engine optimization (SEO), pay-per-click (PPC), and behavioral email targeting.

Core Concepts

• Needs: Physical, social, and individual

Data Warehouse

A Data Warehouse (DW) is a centralized, integrated repository designed for analysis rather than transaction processing. It consolidates data from multiple OLTP systems to support reporting, dashboards, and advanced analytics, serving as a single source of truth for strategic decision support.

Key Properties

The data is curated to be subject-oriented, integrated, time-variant, and non-volatile, ensuring data quality and consistency. Unlike OLTP, the DW is built for read-heavy analytics and historical trends, providing the governance needed for managers to trust the KPIs.

Process Context

Data flows via ETL (Extract-Transform-Load) into the DW, typically in scheduled batches (e.g., nightly). This process standardizes and cleanses data,... Continue reading "Data Warehousing and Business Intelligence Essentials" »

Stages of the Environmental Impact Assessment (EIA)

An Environmental Impact Assessment (EIA) is an administrative sequence that assesses environmental implications before consent and embeds public participation throughout. It begins with the presentation of the initiative to the Administration, which simply opens the procedure and identifies the environmental and substantive authorities and interested parties for subsequent queries.

Screening and Scoping Phases

Next comes the screening or previous studies phase, where the authority decides if an EIA is required and at what depth; the usual output is an Initial Environmental Examination/Evaluation that classifies the project by likely environmental sensitivity and guides the need and level of study....

Core Elements of Sales Management

Sales planning and forecasting: Setting goals aligned with the business strategy.

Sales force structure design: Choosing the most effective organization (territorial, product-based, etc.).

Recruitment and training: Selecting and preparing the sales team to meet market demands.

Motivation and compensation: Applying incentive systems to boost performance.

Monitoring and control: Using KPIs to track progress and correct deviations.

Territory and client management: Assigning territories and managing client portfolios efficiently.

Methods for Sizing the Sales Force

There are three main methods:

• Workload method: Based on the number of customers, visit frequency, and time per visit.
• Sales potential method: Based on market potential

Q1) Solve any 5 of the following: [10]

a) Define the term 'price'.

The term "price" generally refers to the amount of money or value that must be given up in order to acquire a good or service. It is the numerical representation of the exchange value of a product or service in a market transaction. Prices are determined by various factors such as supply and demand, production costs, competition, and market conditions. They play a crucial role in allocating resources efficiently within an economy and influencing consumer behavior.

b) Recall the definition of a retailer.

A retailer is a business or individual that sells goods or services directly to consumers. Retailers typically purchase products from wholesalers or manufacturers and then sell them... Continue reading "Marketing Management: Core Concepts and Strategic Planning" »

The Origins of Networking: ARPANET

ARPANET was the first military-academic network, marking the early development of the Internet in 1969.

Data vs. Information

Data are unprocessed values, while information is organized or analyzed data that becomes meaningful.

Defining Cybersecurity

Cybersecurity aims to protect digital systems, networks, devices, and data.

What was the original purpose of ARPANET?

The original purpose of ARPANET was to enable secure and reliable communication between military and research institutions and allow resource sharing among connected computers.

Why is cybersecurity important for critical infrastructure?

Cybersecurity protects essential sectors like energy, healthcare, transportation, and finance from cyberattacks that could

ASME Code for Design of Shafts

The ASME (American Society of Mechanical Engineers) code provides standard guidelines for calculating the safe diameter of a shaft subjected to different types of loads. The code considers combined effects of bending moment, torsional moment, shock, and fatigue.

ASME Shaft Diameter Determination

According to the ASME code, the shaft diameter is determined using the following formula:

$$d = \left( \frac{16}{\pi\,\tau_{allow}} \sqrt{ (K_b M_b)^2 + (K_t T)^2 } \right)^{1/3}$$

Formula Variables:

• $M_b$ = Bending moment
• $T$ = Torque
• $\tau_{allow}$ = Allowable shear stress
• $K_b$ = Shock and fatigue factor for bending
• $K_t$ = Shock and fatigue factor for torsion

ASME Recommended Allowable Stresses

The allowable shear stress ($\tau_... Continue reading "ASME Shaft Design Standards and Calculations" »
