Learning Objectives

• Explain importance of technology to supply-chain management (SCM)
• Trace the historical "revolution" of supply-chain technology
• Recognise contemporary innovations influencing SCM
• Discuss critical issues when selecting & implementing technology

Key Concepts & Definitions

• Supply-chain technologies: integrated tools/systems that manage the flow of goods, information & finances from origin to consumption, enhancing efficiency, visibility & coordination.
• Digital Supply Networks (DSN): interconnected, data-driven supply chains that replace linear “plan–source–make–deliver” flows with synchronised, sensor-rich networks.
• Industry 4.0: fourth industrial revolution characterised by cyber-physical systems, IoT, big-data analytics, robotics & additive manufacturing.

Importance of Supply-Chain Technology

• Enhanced efficiency: automation reduces manual errors & cycle times.
• Improved visibility: IoT & blockchain enable real-time product status.
• Cost reduction: lower inventory holding, transport & labour costs.
• Better decision-making: analytics provide accurate forecasts & scenario planning.
• Competitive advantage: faster, more reliable service; 61 % of surveyed firms cite tech as a differentiator.
• Innovation & personalisation: 3-D printing, IoT enable customised products & waste reduction.
• Sustainability & compliance: trace environmental / ethical footprints, satisfy regulations & consumer transparency.
• Superior customer service: on-time, fast deliveries increase loyalty.

Traditional vs Digital Supply Networks

• Traditional: linear, siloed stages (Plan → Source → Make → Deliver → Support).
• Digital: sensor-driven replenishment, cognitive planning, smart factories, intelligent supply, connected customer service.
• Questions answered in DSN: “Where is my shipment?”, “Condition at delivery?”, “What happened after quality hold?”

Revolution of Supply-Chain Technology

• Termed “digital supply-chain transformation”.
• Drivers: need for agility, cost reduction, service improvement, rapid market changes.
• Disruption visible in three arenas:
  1. B2C delivery models
  2. Omni-channel retailing
  3. Industry 4.0 manufacturing & logistics

Disruptive Areas & Models

B2C Delivery Models

• Goal: enhance last-mile speed, accuracy & customer experience.
• Tech enablers: drones, crowdsourced delivery platforms (e.g., Grab, Lalamove), real-time route optimisation.
• Example: Amazon Prime – subscription service promising (\leq) 2-day delivery, streaming perks; changed consumer expectations.

Omni-Channel Retailing

• Integrated physical stores, websites, mobile apps, social channels.
• Features: inventory transparency, flexible fulfilment (click-&-collect, scan-&-go, WhatsApp ordering).
• Difference vs multi-channel: channels share data & processes so experience is seamless.

Industry 4.0

• Interdependence with SCM tech.
• Technologies: IoT, big-data analytics, augmented reality (AR), 3-D printing, robotics, cyber-physical systems.
• Timeline: $1784$ Industry 1.0 (steam) → $1870$ 2.0 (electricity, mass production) → $1969$ 3.0 (automation, electronics) → Today 4.0.
• Malaysian examples: Proton (automotive pioneer implementing I4.0); Top Glove (glove maker automating lines, fully computerising operations).

Contemporary Technologies in SCM

Artificial Intelligence (AI)

• Simulation of human intelligence by computers; includes machine learning, deep learning.
• Facilitation: demand forecasting, route optimisation, predictive maintenance.
• Advantages:
  • Accurate forecasts → optimal inventory.

  • Real-time visibility when paired with IoT sensors.
  • Personalisation → increased customer satisfaction.
• Disadvantages/Issues:
  • High initial cost; SMEs may struggle.
  • Requires high-quality data; “garbage-in, garbage-out”.
  • Risk of over-reliance; human oversight still essential.
  • Cyber-security threats.
• Case: Western Digital Malaysia uses AI, analytics, automation to maintain high product quality.

Blockchain

• Decentralised, tamper-proof ledger storing sequential blocks of data.
• Supply-chain facilitation: provenance verification, secure data sharing.
• How it works (simplified):
  1. Transaction requested.
  2. New block created.
  3. Sent to network nodes.
  4. Nodes validate (proof-of-work) & rewarded.
  5. Block added to chain – record immutable.
• Advantages:
  • Transparency & traceability end-to-end.
  • Reduced fraud & counterfeiting.
  • Efficient yet private data sharing.
  • Real-time tracking when fused with IoT.
• Disadvantages:
  • Privacy balance (public vs sensitive data).
  • Regulatory uncertainty.
  • Integration complexity with legacy systems.
  • High initial costs.

Radio-Frequency Identification (RFID)

• Uses radio waves to read electronic tags without line-of-sight.
• Applications: item-level tracking in assembly lines, warehouse management (pallet, case, item).
• Advantages:
  • High accuracy vs manual/barcode.
  • Automated, rapid data capture.
  • Real-time visibility → quick issue response.
  • Cost savings via lower labour, shrinkage.
• Disadvantages:
  • Limited read range; needs multiple readers.
